# Belongs to category:
Sliders

# Description and specifications:
Compensating Insert for a 1/4 Lambda Polarizing/Petrographic Microscope (Quarter Wave Plate) with a Quartz R I Compensator

The insert I'm offering here is from a Meopta RU-2 microscope, but from what I understand, it also fits the DRU-3. I also saw an older Meopta polarizing microscope with a vertically oriented head?and it probably uses the same insert standard.

According to Meopta documentation (DRU-3 microscope brochure), this insert has the following parameters:
- 1/4 Lambda 147 ~ um
- R I 551 ~ um
- Dimensions 4 x 12 mm

# Examples of use
- If you have a polarizing microscope and you are missing these compensators on the slider

# Removed from microscope:
Meopta RU2

# Also compatible with the following microscopes:
- Meopta DRU-3
- Meopta RU2
