Umicore Materials Diamond Like Carbon 3µm-5µm 2Si000002

This is an extremely rugged and abrasion resistant anti-reflection coating for use in the 3-5 micron waveband. These properties make it ideal for external surface applications where extreme environmental conditions will be encountered. It is normally used in conjunction with a high efficiency anti-reflection coating (UCS_Si_01). Spectral - additional Transmission (Average) >92% 3µm-5µm For a 1mm thick witness piece, coated one side UCS_Si_02 and one side UCS_Si_01. Reflection (Average) <5% 3µm-5µm For a 1mm thick witness piece, coated one side UCS_Si_02.
