Leitz

Leica Microsystems GmbH is a manufacturer of superb optical equipment. Leica Microsystems is a successor company of Ernst Leitz that was founded in Germany in 1869.

Leitz Incident Light System

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.

Price £95.00 + vat

Leitz Condenser

This is a Leitz dovetail condenser with a numerical aperture of 0.25 and focal length of 62. From the inversion of the markings it was probably from an inverted unit originally. No iris diaphragm.

Price £37.50 + vat

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.

Leica x100 HCX Objective (3147)

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

Leitz Laborlux 12 Binocular (3103)

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 12 is one of the most popular 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 has a binocular head with periplan x10 eyepieces suitable for those preferring to keep the glasses on. Original Leitz objectives in very good condition x10 EF (0.25), x40 EF (0.65) and x100 EF oil immersion (1.25). The x4 and x25 are parfocal new plan objectives to replace existing objectives that did not still meet the standard required. 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 small scuff area caused by slide being repeatedly added to and removed, and body work in very good condition for its age. A very good buy.

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.

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

Price £75.00 + vat

Leica MZ8 Stereomicroscope on a Long Arm Stand (3211)

This is an excellent Leica MZ8. It is binocular with a continuous magnification range of x6.3 to x50. The MZ8 has a window on the right hand zoom control knob that shows the magnification chosen. It also has the mechanism to set click stops to audibly indicate changes in magnification over 12 steps. The excellent wide field eyepieces have independent focus systems and a rubberised front piece.

The focus block can be attached to the support pole as shown or if the specimen being studied is particularly shallow it can be easily reversed to get closer for focus. The base is heavy for stability and the horizontal system can be moved easily backwards and forwards and up an down the vertical pole. All original and in very good condition. These do not come up on the used market very often.

Price £633.33 + vat

Leitz Dark Ground Condenser (3203)

Complete with its original case, these dark ground condensers do not come up very often. This item is in excellent condition and has the Leitz dovetail fitting so it will fit most of the Leitz range. It has a numerical aperture of 0.80 so would be used dry for x10 and x40 objectives.

SOLD

Leitz Laborlux D Binocular (3230)

A binocular Laborlux D in very good condition. The body work has a few small chips on the paint of the base as would be expected and the stage shows some evidence of slides being taken on and off over the years. We always fully assess the objectives of used microscopes and were appropriate replace them. In this case we have replaced the x4 and x20 objectives with our own plan objectives. They are parfocal with the original Leitz objectives which are x10 EF (0.25), x40 Plan (0.65) and x100 plan oil immersion (1.25). Original Leitz x10 eyepieces. Kohler illumination with 6v 20 watt halogen lamps. Flip top lens condenser.

SOLD

Leitz Dialux 20 Trinocular (3234)

In all honesty Leitz microscope effectively sell themselves such is the quality recognised in these solidly engineered instruments with such excellent optical performance. In our opinion they were without equal in their day. This Dialux 20 has all those features plus the fact that it has been converted to LED lighting and is trinocular to which we have added an adaptor that makes the addition of cameras so much easier. Apart from these additions the microscope is in really excellent condition and is all original. The trinocular head has an image diversion push/pull lever to bring a camera into the optical path. The x10 eyepieces have integral rubber eyecups. The five objectives are all Leitz - x4 plan (0.10), x10 plan (0.25), x25 fluotar plan (0.60), x40 plan (0.65) and x100 NPL fluotar oil immersion (1.32). The body work is excellent for its age and the large rectangular stage of course shows some evidence of slides being taken on and off over the years but in reality it is relatively minimal. The LED conversion fits neatly into the external light box with the brightness control being part of the LED unit rather than the microscope base. Kohler illumination system with the flip top condenser. The best one of these we have seen in a long time.

SOLD

Leitz Labovert Condenser Lens (3229)

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
