iDLC, Durable Coating 8µm-12µm

UCS_GASIR1_05

Productnumber: 2Gas100003

This coating offers exceptional abrasion resistance when deposited onto Umicore’s GASIR5® substrate in the pass band 8-12µm. It is a rugged coating that can withstand severe abrasion. It complies with the environmental specifications of DLC type coatings on Germanium, while offering comparable transmission and lower reflection values. This coating is applied to the outside surface of a lens or window and is normally used with the high efficiency UCS_GASIR5_01 on the second side.
