This is description of this part:
The Leitz PLEZY is an extension adapter for RMS-thread microscope objectives that increases the parfocal focal length from 37 mm to 45 mm, making older objectives compatible with microscopes designed for a 45 mm parfocal standard It is mounted between the objective and the nosepiece/revolver so that optical focus is maintained despite the additional mechanical extension.
Leitz PLEZY differs from extension adapters available on the market in that it features internal anti-reflective optics, ensuring that despite the mechanical extension of the focal length the image quality is not degraded.
What is this part needed for?
- if you want to use older microscope objectives (those with a length of 37 mm) on a newer microscope that requires objectives with a length of 45 mm
