# Description and specifications:
Beam splitter prism for Leica trinocular microscope head.

This specific prism was removed from a motorized trinocular head (manufacturer number 11505145), but it is very likely also compatible with the identical, but non-motorized (manual) head number 11505146.

For the motorized movement system in the Leica 11505145 head, this prism is mounted on a carriage which may differ from the one moving the prism in the manual version of this head (11505146). To use this prism in the trinocular head 11505146, it must be removed (prism only) and re-glued into a new position.

Leica photo-trinocular heads, numbers 11505145 and 11505146 are compatible with microscopes:
- Leica DM4000
- Leica DM4500
- Leica DM5000
- Leica DM6000
- and likely others

Note - the prism shown here has a minor chip on a corner outside the optical path. It does not affect operation and is not visible in the wide field of view.

This service part may solve the following issues with Leica trinocular heads 11505145 and 11505146:
- how to remove fungus from a prism?
- can delamination in a Leica head prism be removed?
- can a mirror inside the prism be repaired if it has oxidized?
- cracked prism in a microscope head

# Examples of use
- as a service replacement part for the full prism
- if the prism in your current head is damaged or heavily degraded
- if you want to install it in another head, e.g. a binocular head to convert it into a trinocular system
- if you need a beam splitter prism for your own DIY projects
