Umicore Materials Diamond Like Carbon 8µm-12µm 2Ge000003

This is an extremely rugged and abrasion resistant anti reflection coating for use in the 8-12µm waveband. These properties make it ideal for external surface applications where extreme environmental conditions will be encountered such as marine environments. It is normally used in conjunction with a high efficiency anti-reflection coating (UCS_GE_01) on the second surface. Spectral - additional Transmission (Average) >89% 8µm-12µm For a 1mm thick witness piece, coated one side UCS_Ge_03 and one side UCS_Ge_01. Reflection (Average) <3% 8µm-12µm Per surface, from a single side coated 1mm thick witness piece, coated with UCS_Ge_03 Angle of Incidence 0°-20° Environmental Properties Adhesion MIL-C-48497A, 08/09/1980, para 4.5.3.1 Adhesion Remark Tape Test Humidity MIL-C-48497A, 08/09/1980, para 4.5.3.2 Humidity Remark 24Hrs, 49°C, 95-100% relative humidity Abrasion MIL-C-48497A, 08/09/1980, para 4.5.5.1 Abrasion Remark Severe, 20 Strokes Eraser Salt spray MIL-C-675C, 22/08/1980, para 4.5.9 Salt spray Remark 200hrs salt spray fog exposure Salt Soln MIL-C-48497A, 08/09/1980, para 4.5.5.2 Salt Soln Remark 24hrs immersion in salt water Solubility TS1888, 01/07/1979, para 5.2.2.1 Solubility Remark 28 days immersion in water Environmental - additional Wiper Test TS1888, 01/07/1979, para 5.4.3 10,000 wipes with windscreen wiper in water/sand slurry.
