# Description and specifications:
Central prism for the Leitz Wetzlar microscope head. This is the central beamsplitter prism.

This prism was removed from a Leitz Wetzlar binocular head P/N 512582 - but exactly the same prisms are also used in other models of binocular and trinocular heads.

It is neither the right nor the left eyepiece prism. It is the central prism that splits the beam towards the right and the left eye.

The last photo in the gallery shows a disassembled Leitz Wetzlar 512582 binocular head, with an arrow pointing to the prism in question and to its position inside the head. This makes the part easy to identify.

Replacing this prism in a Leitz Wetzlar microscope head can be the remedy for the following problems:
- if the prism in your head is mechanically damaged: it may be cracked or chipped
- if the prism to be replaced has a damaged anti-reflective coating: this may be caused by fungus, or the coating may be scratched by improper cleaning
- if discolouration or separation (delamination) is visible inside the prism. This is a cemented prism, and over the years the cement can discolour or come apart in places, which is unfortunately visible in the field of view while working with the microscope
- if the reflective layer inside the prism (usually silver) oxidises and loses its properties in places or completely

Before you decide to use this prism in a Leitz Wetzlar head other than model 512582, first compare the exact dimensions (a millimetre scale is visible in the photos) and, if in doubt, ask on internet groups and forums.
