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

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

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.

An excellent set of Leica infinity corrected M25 screw thread objectives; NPlan x5 (0.12), NPlan x10 (0.25), Hi Plan x20 (0.40), N Plan x40 (0.65), Plan x100 oil immersion (1.25). All corrected for 0.17mm coverslip thickness. Condition excellent.

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.

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

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.

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

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
