High Efficiency Anti Reflection Coating on GASIR® from 8-12µm
Technical Data Sheet UCS_GASIR_01
Application
This coating is the standard anti-reflection coating for use in the 8-12µm waveband. Combining high
transmission, low reflection and moderate environmental resistance, this coating is best suited for internal
surfaces (I.S.) applications.
This coating contains no radioactive material.
