iDLC, Durable Coating on GASIR® from 8-12µm
Technical Data Sheet UCS_GASIR_05
Application
This coating offers exceptional abrasion resistance when deposited onto Umicore’s GASIR® 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_GASIR_01 on the second side.

Transmission
For a 2 mm thick witness piece, coated one face iDLC
UCS_GASIR_05 and one face UCS_GASIR_01
T ≥ 90.0% average for 8-12µm
T ≥ 88.0% average for 8-14µm

Reflection
Per surface, for a 2mm thick witness piece, coated one side
UCS_GASIR_05; AOI from 0o to 20o
R ≤ 1.5% average from 8-12µm
R ≤ 4.0% average for 8-14µm
