Product Description

Overview

ZnSe right-angle prisms are specified for infrared beam folding, beam deviation, and compact optical path control in laser, sensing, and spectroscopy assemblies. This source set describes a custom-drawing ZnSe prism configuration with polished working faces, controlled angular accuracy, and optional coating review for application-specific layouts.

For material background, transmission guidance, and substrate selection notes, see the ZnSe material page. If you are comparing related prism geometries, you can also review our ZnSe prism category.

Why This Geometry Matters

In infrared optical systems, prism performance depends on more than basic beam folding. Engineers usually need to confirm the prism angle, dimensional tolerance, surface finish on the working faces, clear aperture, and coating target together. That is especially important when the prism is being matched to a defined optical layout rather than selected as a general catalog part.

Engineering Notes / Selection Guidance

The source identifies three rectangular faces as polished working surfaces, while the two triangular faces are treated differently for non-working geometry. When reviewing a custom prism, buyers should send the required angle, dimensional envelope, clear aperture, coating target, and mounting reference surfaces together. That shortens drawing review and reduces mismatch risk.
