Product Family Description

TECHSPEC® Diamond-Like Carbon (DLC) Coated Germanium Windows have been designed with durability in mind. Featuring a high efficiency broadband anti-reflection coating on one surface and a specially designed DLC coating on the other surface, these windows feature excellent transmission and environmental resistance. The DLC coated surface is designed to withstand temperature cycling from -80 to +160°F, salt spray for a continuous period of 24 hours, salt solubility for an immersion period of 24 hours, and 5,000 wiper oscillations in a sand and slurry mixture. Further, TECHSPEC DLC Coated Germanium Windows meet the MIL-C-675C requirements for severe abrasion.
