Wide-Angle BBAR Coatings
Deposition Sciences Inc. (DSI)Request Info
Suitable for gimbal windows and sensor detector assemblies, wide-angle
broadband anti-reflection (BBAR) coatings from Deposition Sciences Inc. address
the needs of unmanned aircraft systems for a durable, angle-insensitive (field of
view from 0 to 30°), glare-reducing coating on sapphire substrates. The design
is band-selective so that minimum reflectance can be tuned to a particular detector
package while visibility (glare) in the photopic spectral sensitivity range of the
human eye is minimized. The design delivers an average reflectance of ~2% between
400 and 5000 nm. The coatings are environmentally stable and perform to MIL-C-48497
and MIL-F-48616 standards. Testing is carried out on the coated windows according
to specifications for humidity, salt fog, abrasion, temperature cycle, adhesion,
solubility and cleanability.
