This is description of this part:
LOMO Quartz wedge - wedge compensator with variable optical retardation for Lomo Polam polarizing microscopes
Lomo microscope compensating slider:
Factory marking: none (variable retardation)
Crystal material: Quartz
Optical retardation: continuously variable, from 1st to 4th order of the interference spectrum
Orientation of optical axes: aligned with the insertion direction (retardation increases with insertion depth)
Dimensions:
Total length: 115 mm
Insertion length: 78 mm
Width: 19 mm
Compensating slider in the form of a quartz wedge with variable, increasing optical retardation. Allows precise, continuous adjustment of the compensation value by sliding the wedge within the microscope accessory slot. Used for accurate determination of the interference color order of observed specimens and for precise measurement of crystal birefringence.
What is this part needed for?
- If you have a polarizing microscope and you are missing this compensator on the slider
- If you have this slide, but it's damaged (e.g., delamination)
