Olympus PE 2.5X 125 Microscope Photo Eyepiece / Projection Lens 25.0mm (Rare) 1

Description

PE Eyepiece
This is the most recent range of photo eyepieces, designed for use with trinocular versions of Olympus compound microscopes that take the UIS and UIS-2 series of infinity-corrected objectives (including the AX, BX, CX, CKX, IX and MX series), and with trinocular versions of the Olympus SZX7, SZX9, SZX12 or SZX16 infinity-corrected stereo microscopes. They fit inside the circular dovetail at the top of the U-DPT, U-SPT, U-VPT, IX-SPT and IX2-SPT photo tubes.
The PE photo eyepieces are available with 2×, 2.5×, 3.3×, 4× and 5× magnifications; the 2.5× eyepiece is intended for use with 35 mm cameras.

For digital and for 35 mm film, the picture magnification on the sensor or film is determined by the formula:
PE eyepiece power × objective power
The large format film camera backs include a relay lens, and the picture magnification on the film is determined by the formula:
3 × PE eyepiece power × objective power
The PE photo eyepieces are not suitable for use with the 160 mm and 210 mm objectives used on the BH-2 and earlier microscopes, nor are they suitable for use with the MSPlan and Neo SPlan infinity metallurgical objectives for the BH-2. They have a wider diameter than the FK and NFK photo eyepieces, so it is impossible to use them in the BH2-TR30 trinocular head or in the PM-ADF eyepiece adapter.
