Leitz Projection Attachment

Before the digital world with its cameras and projection devices arrived, it was somewhat unique to be able to share microscope images with others. This Leitz projection attachment was designed to do just that. It clamped over the eyepiece of a microscope and its prism deflected the image that the microscope saw to a screen. A part of our microscope history.

Price £41.67 + vat

Leitz Zernike Phase Contrast Condenser

This is a Zernike Phase Contrast condenser that will fit Leitz SMLUX  microscopes. Four position phase rings with a bright field option. Iris diaphragm and phase rind adjustment controls. Condition very good.

SOLD

Leitz Vintage Stereomicroscope

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 collectors 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!

Price £416.67 + vat

Leitz Ergonomic Binocular Head

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.

Price £187.50 + vat

Leitz Dialux 22 Trinocular

An excellent example of this stalwart Leitz microscope that has the benefit of having an LED illumination conversion. It is all original apart from this improvement. Trinocular head with x10 periplan GF eyepieces and a five position  turret with 160mm objectives. x4 plan (0.10), x10 plan (0.25), x25 EF  (0.50), x40 plan (0.65), x100 EF (1.25). Flip top condenser and a field iris allowing Kohler illumination. Large mechanical stage with drop down coaxial controls. The general condition is very good for its age with just a few scuffs on the edges of the base (probably caused by watch straps or bracelets) and a small area of wear on the stage from the movement of slides on and off. Otherwise this is a fine microscope.

SOLD

Leica DMLS Binocular

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.

Price £541.67 + vat

Leica EZ4 Stereomicroscope

This is a new stereomicroscope that is complete with its Leica dust cover. Quick start guide and  Leica badged cleaning brush and is unused. As well as having the expected excellent Leica optical performance, and the continuous zoom magnification runs from x13 to x56.  The EZ4 has an ingenuous 7-way flexible and adjustable LED illumination system with transmitted, incident, and oblique lighting that allows for high contrast viewing of any type of sample. The lights can be switched independently or combined, and can be controlled via the membrane switch towards the back of the base. The EZ4 contains a Greenough optical system and because of the parfocality of the optical system, the image remains in focus from the lowest magnification to the highest. The membrane switch and glass stage plate are sealed into the surface to prevent the accidental entry of liquids that could damage the transmitted-light illuminator. The eyepieces are sealed in place to prevent loss or damage and   provide optimal viewing conditions, whether you wear spectacles or not.  The 60° viewing angle is equally ergonomic for all heights and  the eyepiece tubes adjust simultaneously from 50 to 75 mm to provide the correct personal interpupillary distance for all users. An exceptional price for a new quality stereomicroscope.

SOLD

Leica DMLB Trinocular

This is an excellent Leica DMLB trinocular microscope, a substantial instrument in good condition. The trinocular head has Leica HIC Plan x10 eyepieces that are corrected to allow glasses wearing if necessary and are complete with integrated eyecups.

Large rectangular stage with drop down coaxial controls that shows minimal evidence of slide movement. Low position coaxial coarse and fine focus controls. The 12v 30watt halogen light source is housed in a small external light box at the back of the microscope. The lighting controls are in the base of the microscope aligned on the right hand side and controls brightness and the Kohler setting. The body work is in excellent condition. A opportunity to obtain a modern research standard microscope.

SOLD

Leitz Laborlux S Binocular

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.

 Price £375.00 + vat

Leitz SM-LUX Trinocular

The Leitz SM-Lux was an extremely well built model from the Leitz stable and trinocular versions are now quite hard to come by. This is a very good example at a very competitive price. Trinocular head with Leitz periplan x10 eyepieces. Leitz x10 fluotar (0.25) and x40 EF (0.65) objectives with modern x4 semi plan and x25 and x100 (oil immersion) plan objectives. Mechanical stage with coaxial drop down controls and a focusing condenser with flip top lens. Integral halogen 6v 10 watt lamp housing with full Kohler illumination system. The focus system is the Leitz characteristic fine and coarse focus within the same focus control which makes using it a joy! The body work finish and stage surface is very good indeed for its age.   

 Price £329.17 + vat

Leitz Dialux 20EB Trinocular

Leitz microscopes are quite simply a quality act, and even though they are (with the Leitz rather than Leica logo) advancing in age you can’t wear out a microscope by looking through it! The 20 EB had the advantage of being a large sturdy microscope with a large base, the lamp housing is internal so there is no need to accommodate a light box to the rear. This particular instrument is equipped with a Zernike phase contrast condenser and a mix of bright field and phase contrast objectives. The microscope is all original which of course adds to its intrinsic value. Trinocular head with a three way lighting control and x10 periplan eyepieces with integrated eyecups that are also suitable for spectacle wearers. Objectives x4 plan (0.10), x10 plan fluotar (0.30), x25 plan phase contrast (0.50), x40 plan phase contrast (0.65), x100 EF (1.25). This microscope has excellent body work and the stage shows very little evidence of slide movement. 20EB’s this good do not come along often these days.

Low position coaxial coarse and fine focus controls. Kohler illumination system with an integral 12v 30watt halogen lamp system. The general condition of the stage and body work is very good apart from the small paint chips on the base which does not subtract from its excellent optical performance.

SOLD

Leitz Parallax Photography System

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.

Price £112.50 + vat

Leitz Diamond Slide marker

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

Leitz Immersion Oil Bottle

This vintage item would grace the work bench of any Leitz microscope enthusiast. Finished in amber and clear glass this is an oil immersion dispenser with the Leitz name pressed into the glass. As would be expected it has the Leitz quality with a spring loaded dropper system. Not many of these are survived intact.  

SOLD

Leitz Laborlux K Trinocular

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.

Leica ATC 2000 Binocular

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.  

Price £291.67 + vat

Leitz SM-LUX Binocular

The main advantage of this Leitz microscope is its conversion to LED illumination. It has also had three of its objectives replaced with new plan objectives of our own make. It is optically excellent with daylight spectrum Kohler illumination. The binocular head has x10 periplan eyepieces and the objectives are Leitz EF x10 (0.25) and x40 (0.65) with new Brunel plan x4 (0.10), x25 (0.40) and x100 (1.25). Mechanical stage with drop down controls and a focusing substage condenser. There are a number of small paint chips to the body work and also the head, but this is not reflected in the optical and mechanical performance, although it is reflected in the price    

SOLD

Leitz Dialux 20 Trinocular

An all original Dialux 20 in extremely good condition apart from an area of scuffing on the stage from slide movements. The stage itself is particularly large for a Dialux 20 and has substantial drop down chrome  movement controls. The substage condenser has a flip top lens to facilitate the field of view for both high and low power objectives. The trinocular head has the usual image direction adjustment  and is equipped with periplan x10 eyepieces, and we have included a trinocular tube converter which will allow most cameras to be fitted  via the appropriate adapter. The five Leitz objectives are all NPL Fluotar and in good condition, x6.3 (0.20), x10 (0.30), x16 (0.45), x40 (0.70) and x100 oil immersion (1.32). The relative NA figures show their quality. Kohler illumination with an external light box and transformer. 12v 100 watt halogen lamp.

SOLD

Leitz Orthoplan Trinocular

As well as being a fine microscope this is now really a collector’s piece. The Orthoplan was introduced as the flagship model in 1966 and continued in production essentially unchanged until 1991 which attests to the original design which was the first designed for a field of view of 28mm - more than twice the area of standard microscopes. This particular unit would date from the later years of this period because of the livery of off-white/ivory colour. The body work and stage are excellent considering its age. All Orthoplans had 170mm tube length objectives for bright field. The five objectives here are x2.5 plan (0.08), x4 (0.12), x10 plan (0.30), x40 (0.65) and x100 plan oil immersion (1.32). The trinocular head has the 30mm wide field eyepieces with the interocular distance control by a thumb gear system and there is image direction adjustment for the trinocular tube which we have added an adapter to to more easily accommodate a camera compared to the standard very wide tube. The external light box houses a 12v 100 halogen lamp with full position control and the original Leitz power box. This is a fine microscope

SOLD

Leitz Dialux 20EB Trinocular

There are two things to say about this microscope firstly the body work and stage surfaces are truly excellent considering its age but secondly the voltmeter on the front no longer registers changes but this does not in any way effect its electrical performance or the  illumination system. Everything about this microscope is original. The trinocular head has the usual image diversion system for camera work and we have added a trinocular adapter to make camera connection much easier than the very wide Leitz trinocular tube. The eyepieces are x10 periplan. Objectives EF x4 (0.12), x10 plan fluotar (0.30), x16 plan fluotar (0.45), x40 NPL fluotar (0.70), x100 NPL fluotar (1.32). The NA numbers show this is a good set. Large mechanical stage with coaxial drop down controls. Condenser with flip top lens. Integral 6v 20 watt halogen Kohler illumination system. The general condition of this microscope shows that it was almost certainly owned by an individual who cared rather than a laboratory ‘workhorse’. A very nice microscope

SOLD

Leitz Dialux 22 Binocular

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
