Optical ZnSe Right Angle Prisms

Name: Optical ZnSe Right Angle Prisms
Brand: Henan UM Optics Ltd
Availability: InStock

Description

Znse right-angle prisms are employed for deflecting light paths or for deflecting the image formed by an optical system by 90°. Znse right-angle prisms usually have a large contact area and angles of 45° and 90°, which make them easier to install and have better stability and strength against mechanical stress.

Frequently Asked Questions

What are the key optical properties of ZnSe (zinc selenide) that make it suitable for right-angle prisms in infrared applications?

ZnSe offers broad infrared transmission (0.5–22 μm), low absorption in the MWIR/LWIR spectrum, high refractive index (~2.4 at 10 μm), and minimal scatter losses. Its chemical stability and durability further enable reliable prism performance in harsh environments.

How does the 90° tolerance of a ZnSe right-angle prism impact alignment precision in optical assemblies?

A tight angular tolerance (e.g., <1 arcminute) ensures minimal deviation from the ideal 90° reflection, critical for maintaining beam path accuracy in interferometry or LIDAR systems. Deviations cause beam walk-off, affecting system resolution.

Why might a ZnSe prism with a dielectric mirror coating on its hypotenuse be preferred over an uncoated TIR design?

A dielectric coating ensures >99% reflectivity across specific angles and wavelengths, bypassing the critical angle limitations of total internal reflection (TIR). This allows flexibility in incidence angles and broadband performance.
