The ATC has coaxial coarse and fine focus control that moves the objective turret up and down rather than the stage. Objectives x4, x10, x40 and x100 (oil immersion|) with x10 wide field eyepieces Mechanical stage with drop down coaxial controls and double vernier scale.  6 volt 20 watt halogen illumination with brightness control. Focusing and centring substage condenser and the stand has a cleverly designed carrying handle at its top. Good condition apart from a few small paint chips along some of the edges of the base

Leitz Laborlux D Trinocular

This really is one for the collectors who ‘know their onions!’ We have not seen one of these in such good condition before. This trinocular microscope has a serial number of 741280 which places it at about 1968. The body work is immaculate for its age and it is equipped with the Leitz  Pv phase system which was an ingenious method designed to avoid copyright law at that time. So, the specification has a Pv phase condenser with the following 170mm tube length objectives. Pv x10 (n.a.0.25), Pv x25 (0.50), Pv Apo x40 with coverslip correction (0.70) and a Pv Apo plan x90 oil immersion lens (n.a.1.32). Together with x10 eyepieces. The unit is served by a Leitz transformer box which makes the unit all original and provides a 6v 15 watt halogen lighting system. This will not stay here for long.

Leitz Ortholux Trinocular

This is a Leitz Ortholux that has been built up over the years all with genuine Ortholux accessories. It is currently configured with a polarisation system above the stage, although the stage itself is the standard square version. The trinocular head is the Pol-tube combined type with standard eyepieces for the binocular with 30mm photoeyepiece in the trinocular tube. The head has an inbuilt analyser with 180 degree rotation, clamp and scale, Bertrand lens in centring and focusing mount. The photographic tube is equipped with an iris diaphragm and a top analyser with index. Beneath the stage is a standard bright field condenser and to achieve polarisation there is a separate polarising filter that can be placed over the transmitted light. This unit has both incident and transmitted light sources and an additional turret with incident light path with double iris. The condition of the stand is generally very good with just a few paint chips here and there. The current objectives are NPL x10 P (0.20), x50 P (0.85), Pv Apo x40 (0.70) with coverslip thickness adjuster, Pv x25 (0.50) and Pv x10 (0.25). x10 periplan eyepieces. This Ortholux was being built up into a Universal Ortholux by the previous owner who sadly ran out of time. It needs someone to appreciate its place in the history of Leitz microscopy and to complete its final specification.
