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.

A really good example of this Leica laboratory workhorse and in very good condition. This unit has the added benefit of an ergonomic head with allows the height of the binocular head to be adjusted to suit the individual. x10 wide field eyepieces. Infinity corrected M42 screw thread C Plan objectives x4 (0.10), x10 (0.25), x10 (0.25), x20 (0.40), x40 (0.65) and x100 oil immersion (1.25) and all corrected for 0.17mm thickness coverslips. Kohler illumination with a 12v 30watt lamp. Flip top condenser. Large mechanical stage with drop down coaxial controls. Coaxial coarse and fine focus controls. General condition very good.

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 an excellent x2.5 Leica plan fluorite infinity corrected objective. Numerical aperture 0.07 and RMS screw thread.

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 must stem from that exact date as it has the Leica motif on the front of the base but still carries Leitz on the side of the stand. 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. The padded arm rests on the base recognised the effect that watches and bracelets could have on a paint finish and added to the look of the instrument. This good example has a binocular head with periplan x10 eyepieces suitable for those preferring to keep the glasses on. All original Leitz objectives in very good condition x4 (0.10), x10 (0.25), x25 (0.50), x40 (0.65) and x100 oil immersion (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 and body work in very good condition for its age. A very good buy.

Leitz were perhaps better known as quality compound microscope manufactures rather than stereomicroscopes until they merged with Wild. This however is an excellent Leitz stereo that is a collector's piece that says 'Leitz' from every perspective. The microscope has a system of sliding 'back to front' objective pairs with the x1 being static with space for two other magnifications. In addition to the x1, the options are x2, x4, x8, and x12. There are two pairs of eyepieces - x12.5 and x18. This gives a magnification range of x12.5 to x216. As would be expected the quality of mechanical construction is exemplary. There is no built-in illumination and the plain stand has alternate black or white plates that slide into the base and clips. Everything about this microscope is original and in excellent condition. We have never seen one of these before and are very tempted to keep it ourselves!

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.

This item really belongs in the Antiques section of this web site. It would date from 1900 or so. It consists of an RMS screw thread and mimics an objective except that it has a small diamond mounted at its end and slightly off centre so when lowered onto the slide/coverslip and rotated it leaves and etched circle for future reference. Complete with original 'objective' pot

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

This is a very rare Leitz product. It is an ergonomic head that allows angle of the eyetubes to be adjusted through about 30 degrees to suit the height of the individual. It will fit the following Leitz models Laborlux K, 11, 12, and D, Dialux 20, 20EB, 22 and 3A. Eyepieces not included. Condition excellent

This is a Leica infinity corrected HC Plan Fluotar x10 objective with a numerical aperture of 0.30. M25 screw thread. Condition excellent.

The Laborlux K models - all original with a trinocular head are now quite a rare item For its age this is in very good condition with inevitable scuff marks on the stage and some small paint chips to the base. Optically it is excellent with EF x4 (0.01), x10 (0.25), x40 (0.65) and an NPL fluotar x50 oil immersion (1.0) and an EF x100 oil immersion (1.25). The presence of a x50 oil immersion strongly suggests that it was used in a pathology haematology laboratory where this lens would have been used for examining blood smears. Flip top focusing condenser and large mechanical stage with drop down coaxial controls. 6V 20 watt quartz halogen Kohler illumination system The lamp is housed externally. The trinocular head has GF periplan eyepieces with the usual controls to divert images to a camera. We have fitted the trinocular tube with an adapter which will enable virtually all cameras to be fitted via the appropriate adapter for the camera make.

The Leica ATC was an excellent attempt to bring Leica quality into the student undergraduate market and it involved the optical qualities of both Reichert and American Optical and the microscope was made in the AO factory in Buffalo USA and was possibly the last 'non-Chinese' manufactured microscope aimed at this market. It has some interesting distinctive features. The objectives are infinity corrected and the focus is achieved by moving the objective turret up and down rather than the stage. This particular example has been well used and there are several scuff marks to the paint on the base. This apart it is optically excellent with x4, x10, x40 and x100 (oil immersion) infinity corrected objectives and the binocular head has wide field x10 eyepieces. The ATC also has Kohler illumination which is again a plus point for the range. Illumination is by a 6v 20-watt quartz halogen lamp. Good value.

At the time there would have been very good marketing reasons behind the decisions to make such a range of the Dialux microscope - 20, 20EB and 22 models. It was probably based around the the light source arrangement. The Dialux 22 has an external lamp housing because of the 12v 100 watt lamp and the heat this would cause if it was internal. This microscope is in very good condition and is all original including the transformer box. The binocular head has x10 periplan eyepieces and the objective turret has x2.5 plan (0.08), x10 (0.25), x40 plan (0.65), NPL Fluotar x50 oil immersion (1.00) and EF x100 oil immersion (1.25). Kohler illumination. The body work and stage are in very good condition. This is a fine microscope
