Leitz/Leica

This is one for the collectors. An all original Leitz stand-alone light source. Pole base stand with a lamp unit that has tilt, focus and a filter slot. Original Leitz transformer unit. In very good condition for its age

A rarely found accessory in the used market. a leitz teaching head with integral moving pointer, will attach to any modern leitz compound microscope stand and will except two binocular heads (not supplied).

This is a Leitz Wetzlar photography system in full working order with two cable releases. Complete with its original box it looks hardly used and would date from the early 1950's. It has preset shutter speeds and the focusing eyepiece has cross lines to aid focus. It is rare to find complete units in good condition these days. A collectors piece.

An incident light system that will fit the Ortholux and SM-Lux microscopes. Double iris and filter slots. Condition fully functional but cosmetically average hence the price.

This is still a current Leica model and this individual unit is in pristine condition and presents as new. The DM500 in many ways represents an innovation from Leica. It is based on the same optical platform as the Leica Microsystems research line but is constructed in such a way to minimise as far as possible the need for the user to set things up all the time. It is an ideal instrument for those who want to combine the exceptional quality of Leica optics with a microscope that is constantly 'plug and play'.
The DM500 has a pre-centred, pre-focused Abbe condenser that eliminates the need for adjustments. It has a slot for phase contrast and dark field sliders (not included). The LED lighting is designed to give even illumination across the full field of view without the need for adjustment. It has a substantial mechanical stage with coaxial drop-down controls and an easy-to-use slide retention clip.
The microscope has infinity corrected M25 thread plan objectives x4 (W.D. 26.2mm), x10 (W.D. 7.8mm), x40 (W.D. 0.31mm) and x100 oil immersion (W.D. 0.10mm). 45-degree head with high eye point wide field x10 eyepieces with integral eye guards.
Coaxial low position coarse and fine focus controls. The back of the microscope has an integrated carrying handle and a neat storage space for the electrical lead. This is a fine microscope. If you have ever wanted an automatic Rolls Royce that can drive itself, in the microscope world this is it.

This is really a collectors item, a crosshair slide for centring circular rotating microscope stages by Ernst Leitz. Dates from about 1920 and in very good condition

This is one of the most sought after Leitz microscope accessories. The term phase contrast was the subject of copyright laws for some time after it was first described by Zernike. Leitz produced their own optical process which used the Heine condenser that could produce phase as well as dark field with the specific Pv objectives. Brunel Microscopes Ltd was first registered in 1986 and we have never obtained this complete set before. The Heine condenser has with it four Pv objectives.
Pv Apo x40 with coverslip thickness adjustment (n.a. 0.70)
Pv Apo x90 oil immersion (1.32)
Pv Fl x70 oil immersion (1.15)
Pv x10 (0.25)
This is one for the collectors and Leitz enthusiasts

The Leica DM2000 is a high-performance upright microscope tailored for pathology, cytology, IVF, and other clinical diagnostics. Designed for precision and comfort. This particular model is in very good condition and has an ergonomic head that can easily be adjusted for height. It is a substantial microscope with a large mechanical stage with long drop down coaxial controls and a platform surface protection. As would be expected it has a full focusing substage condenser with iris diaphragm and low position coaxial coarse and fine focus controls.
Four M25 infinity corrected objectives on a five position turret. Hiplan x4 (0.10), x10 (0.25), x20 (0.40) and x40 (0.65) with super wide field x10 eyepieces.
The Kohler illumination is by 12v 30 watt quartz halogen.
This is a large microscope that was built to last and will take Leica accessories for phase contrast, polarisation and indeed additional objectives. An opportunity to obtain a research level microscope at a very competitive price.

The Leitz Ortholux is probably one of the most collectable of the Leitz range. These were made at a time when good old-fashioned robustness and structural stability were key. For its size this is a relatively heavy microscope. The important thing is that it is all original apart from the transformer box which has to be new for current electrical regulations.
The overall condition is excellent. in fact we have not seen one as good as this for a long time. From the serial number it dates from about 1967 or so. We have added a little bit of 2025. It has a trinocular adapter which means it can take any camera on the trinocular tube with the appropriate adapter.
170mm Leitz objectives x10, x16, x40 and x100 (oil immersion). Full mechanical stage with coaxial drop down controls, and the surface shows a few but relatively little marks from slides over the years. The x10 Leitz eyepieces have independent focus controls with interocular and dioptric adjustments. Full Kohler illumination. A fine microscope from the 'heyday' of quality microscope production.

This is one of the Leitz classic microscopes and in very good condition. The only negative is that the microscope base has some paint loss on the edges of the base which is always the result of watch straps or bracelets from the original owner. The features of this original microscope are listed below. The only thing that is not original is the transformer box which has been replaced by a modern unit that meets the current regulations.
The turret has five Plan Fluotar Leitz objectives with particularly good numerical apertures x10 (0.30), x16 (0.40), x40 (0.70), x50 oil immersion (1.00) and x100 oil immersion (1.32). The eyepieces are Periplan x10 wide field that are suitable for spectacle wearers.
It has a particularly large stage with coaxial drop down controls and double vernier scales. Flip to condenser and of course Kohler illumination with a 12 v 50 watt halogen system in the external light box that is controlled by a modern transformer box that meets current safety standards

This is an M45 screw thread Leica objective of excellent quality. It is a x100 plan fluotar oil immersion objective that is infinity corrected with a numerical aperture of 1.30 and corrected for a coverslip thickness of 0.17mm. These do not become available too often these days. The general condition is excellent

This is a condenser lens from the Leitz Labovert that is the classic inverted microscope that Leitz made to look rather similar to a Laborlux, except that the objective turret was below the stage with the light system above. This has the numerical's A0.30 - S50 and a part number of 513635

The Leica Microsystems ES2 stereomicroscope was designed as a University student system. It is easy to use, durable and features high optical and illumination quality. It is a two step system offering x10 and x30 magnifications controlled by a click stop mechanism.

It has x10 integrated high eyepoint eyepieces at an angle of 60 degrees for comfort. It has a working distance of 100mm.

Integrated LED incident and transmitted illumination controlled by separate switches. Condition is pristine. An excellent opportunity to obtain the quality of Leica optics at an affordable price

An original Leitz stage micrometer with a scale that is 2mm divided into 200 divisions. Not only does it have the original German labels on the slide but it is complete with its original box

An excellent x40 phase contrast Phaco Leitz objective with standard RMS screw threat. Numerical aperture 0.65 and corrected for 170mm tube length and 0.17mm coverslip thickness.

An excellent x100 phase contrast oil immersion Phaco 3 Leitz objective with standard RMS screw threat. Numerical aperture 1.30 and corrected for 170mm tube length and 0.17mm coverslip thickness.

An excellent NPLx100 oil immersion Leitz objective with standard RMS screw threat. Numerical aperture 1.30 and corrected for 170mm tube length and 0.17mm coverslip thickness.

This is a x8, 30mm diameter eyepiece with a cross-hair graticule. It is for the Dialux Polarising microscope with a monocular head, these had 30mm diameter eyetubes and the cross hair was to assist centring of the polarising objectives. Condition excellent, it looks virtually unused.

Made by Leitz for micro projection. The eyepiece has a long focal length(79mm) for the projection of the microscope image. It has a standard field of view index (22) but are not suitable for visual observation similar to a photoeyepiece

In really excellent condition this is a Leica x2.5 HCFL Plan objective. M25 screw thread, infinity corrected with a numerical aperture of 0.07

The optical and mechanical performance of Leica microscopes is self evident in the name. The M60 in particular gives an excellent optical performance. This particular unit is in excellent condition throughout. The zoom body has a x1 plan objectives with x16 wide field eyepieces that give a zoon range of x10 to x64. There is an adjustment lever that can make this either click stop or a smooth operation. This unit has superb lighting options. The large square base has rack and pinion throughout the focus range with coaxial coarse and fine controls. The stand has a large central glass dissection area.
The illumination options are provided by the Leica KL 1500 fibre optic unit and a Photonics ring light. The flexible fibre optic arm from the KL 1500 inserts into the back of the base and an internal moving mirror system allows an easy transition between bright field and dark field transmitted illumination. The KL1500 has colour temperature and separate brightness controls
The Photonics ring light has complete or sector illumination options with brightness controls that allow a wide range of incident lighting options.

This is a seriously good stereomicroscope of a standard that we do not often get through our hands.

This is a Leica fibre optic halogen light source with brightness control and a Swiss made (Volpic) fibre optic ring light that will clamp onto any stereomicroscope with a parallel sides bottom lens up to a maximum diameter of 65mm. Condition excellent

A Leitz polarising analyser filter that will slot into the space above the objective turret of Leitz Laborlux microscopes. In very good condition with little evidence of dilapidation.

In very good condition, this is a Leica focusing spot light for use with stereomicroscopes. Quartz halogen lamp unit with brightness control.

Berek tilting compensator wave plates are a rare find these days particularly with their original box. These were capable of precise 1/10-degree measurement and three types were listed in the Leitz 1971 catalogue at a price then of $453! This fine example is in excellent condition. The Berek compensator is an optical device that is capable of quantitatively determining the wavelength retardation of a crystal, fibre, mineral, plastic film or other birefringent material. Provided the thickness of the material can be measured, a Berek compensator can be utilized to ascertain the birefringence value. The compensator operates by measuring the rotation angle of a calcite or magnesium fluoride optical plate cut perpendicular to the optical microscope axis. This is a very rare item that is reflected in the price. Condition excellen

Leitz objectives need no introduction. This is an excellent example of a Plan objective x2.5 corrected for 170mm tube length with a standard RMS screw thread and a numerical aperture of 0.08. Condition excellent

Pv objectives were designed to provide phase contrast and dark field illumination with the Leitz Heine condenser. The terminology at that time avoided the use of the term phase contrast because of initial copyright issues that pinned the term to Zeiss for a period in the 1950's. This objective is very rare being a x70 oil immersion lens with a numerical aperture of 1.15. Corrected for a 170mm tube length and 0.17mm coverslip. Standard RMS screw thread. Condition excellent.

These specialist Leitz accessories are getting to be somewhat rare animals these days. This is a Mica Compensator with a ¼ wavelength plate. In excellent condition.

This is a relatively rare objective. Low power objectives are more difficult to manufacture as curvature of the lenses is critical. This is a plan x2.5 corrected for 160mm tube length with a standard RMS screw thread and a numerical aperture of 0.08. Condition excellent

This is a Leitz condenser with a rotating polarising filter as an integral element. It has the standard lateral adjusters for setting up Kohler illumination, an iris diaphragm and a flip top top lens with a numerical aperture of 0.90. Condition excellent.

In 1986 Leitz re branded itself as Leica a name formed from the first three letters of its founder (Leitz ) and the first two of the word camera for which it was also renown. This SM-LUX is all original and in very good condition for its age. To start with the negatives - the edge of the base on the left-hand size has some of the paint worn. This tells us that the previous owner was probably left-handed. Apart from that there is not a lot to be negative about. The microscope has full Kohler illumination with a field iris diaphragm a mechanical stage with double vernier scales and a sub stage condenser with flip top lens and lateral adjustment. Tungsten lamp illumination 6v 15watt with click stop brightness control.
170mm all original Leitz objectives x2.5 (0.07), NPL x10 (1.25), x40 (0.65), x100 oil immersion (1.25). The turret has spaces for five objectives and a blank is in the vacant place. A part of Leitz history that gives an excellent optical performance

In 1986 Leitz re branded itself as Leica a name formed from the first three letters of its founder (Leitz) and the first two of the word camera for which it was also renown. This Laborlux S is one of the most popular of the Leitz microscopes. There would be few pathology laboratories throughout Europe that would not have used these models as their standard workhorse as they combined a sturdy-built quality with excellent optics. This good example is all original and has a binocular head with periplan x10 eyepieces suitable for those preferring to keep the glasses on. Original Leitz objectives in very good condition and with good numerical apertures where it matters. x4 EF (0.12), x10 Fluotar (0.30), x20 EF (0.50), NPL Fluotar x40 (0.70) and EF x100 (1.25). Coaxial low position coarse and fine focus controls. Kohler illumination with a 6v 20 watt lamp in an external light box. Stage surface, apart from a very small scuff area caused by slides being repeatedly added to and removed, The body work is in very good condition for its age. A very good buy. Highly recommended a fine-looking microscope

The microscope is still a current Leica model and this individual unit is in pristine condition and presents as new. The DM500 in many ways represents an innovation from Leica. It is based on the same optical platform as the Leica Microsystems research line but is constructed in such a way to minimise as far as possible the need for the user to set things up all the time. It is an ideal instrument for those who want to combine the exceptional quality of Leica optics with a microscope that is constantly ‘plug and play’.The DM500 has a pre-centred, pre-focused Abbe condenser that eliminates the need for adjustments. It has a slot for phase contrast and dark field sliders (not included). The LED lighting is designed to give even illumination across the full field of view without the need for adjustment.. It has a substantial mechanical stage with coaxial drop down controls and an easy to use slide retention clip. The microscope has infinity corrected M25 thread plan objectives x4 (W.D. 26.2mm), x10 (W.D. 7.8mm), x40 (W.D. 0.31mm) and x100 oil immersion (W.D. 0.10mm). 45-degree head with high eye point wide field x10 eyepieces with integral eye guards.

The crowning glory of this instrument is the Leica ICC50 digital camera that fits between the microscope body and binocular head. Optically this has to be one of Leica's most notable achievements. Its position ensures complete parfocality between the image viewed down the microscope and the focus of the captured images. In order to maintain this the individual eyetubes do not have independent focusing so that the parfocality is always maintained. The ICC50 camera can be used in three ways.

Either connected by HDMI directly to a monitor or TV (with an HDMI in port),
Independently with images saved directly to an SD card (which can be done with confidence because of the parfocality),
Connected to a Windows IOS computer (including Windows 11) using the Leica LAS EZ software, which is supplied as are all necessary cables and an SD card. This allows still image capture, video clips and the ability to make direct measurements through the software.

This really is an exceptional microscope unit. We would buy it ourselves if we didn’t already own it.
