Leitz Laborlux 11 Binocular

The Leitz Laborlux 11 was generally regarded as one of the ‘workhorse’ microscopes of the Leitz range. This particular model is binocular with periplan x10 eyepieces. Full mechanical stage with drop down controls. Kohler illumination with brightness control. Objectives Plan x20 and x100 (oil) immersion and Leitz x10, x40 and x50 (oil) immersion 160mm tube length objectives. The body work is very good and all together this is a fine microscope from the ‘hay day’ of the Leitz era.

Leitz SM-LUX Trinocular

Leitz microscopes have stood the test of time, and this is a good example of a unit that has been modified to bring it a little bit up to date. It has had its light source very cleverly converted to LED with a rheostat brightness control that does not materially change the look of the microscope. From the top down it has a trinocular head with x10 periplan objectives. Leitz objectives x4, x6.3, x10 and x40 all corrected for 170mm tube length. Mechanical specimen driver. Flip top condenser with lateral adjustment. Kohler illumination with field and substage iris diaphragms. The body work is very good. An excellent opportunity to obtain a classic microscope with a modern twist.

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 1/7a Objective

A good vintage Leitz objective with original objective case. Marked as 1/7a this is approximately - using the Leitz literature - a x54 oil immersion lens with a numerical aperture of 0.95. RMS screw thread and corrected for 170mm tube length.

Price £45.83 + vat

Leitz Diaplan Body

The Diaplan was the largest of the Leitz range and particularly well built. This body is offered for spares only as the electrical system (although complete) has failed. However the body work is really good for its age and would be ideal for parts for less well ‘journeyed’ units. The parts that are missing are the rear light box, objectives (5 position turret is present), head and the stage slide ‘claw’.


Leitz Dark Ground Stage Attachment

This is a Vintage/Antique Leitz stage attachment which is designed provide a dark ground image with lower power objectives. Mounted on a plate that would seat on top of the stage and has two slide clips. Original lined case. Probably dating from 1920 or so. Excellent condition for its age.
