Infrared Optical Hemispheres (Domes)

Infrared Optical Hemispheres (Domes)

Precision Polished Domes and Hyper Domes

Available from CaF2, UVFS, Si and ZnSe

Up to 12mm Diameter

Overview

LightPath Technologies, through its subsidiary ISP Optics, has been producing domes for over 25 years. Manufactured in our ISO 9001:2015 and ITAR certified facility, domes are fabricated using deterministic CNC machine tools then polished into its geometrical shape. Optical domes are commonly used for protecting cameras and optical sensors but provide a clear field of view to the outside environment.

If you have an airborne imaging system that requires a high quality layer of protection, give us a call.
