Avian-EP Black
Avian-EP Black is an electrochemical process that can be applied to almost any substrate including plastic or glass. The coating is highly diffuse but somewhat fragile, so its use in applications that require handling of the optical surface are not recommended.
Optically, Avian-EP Black is very highly absorbent in the UV-Vis-NIR and has better range than Avian-DS Black (above). The coating remains 'black' out to 7-8 microns.
As with Avian-DS Black, Avian-EP black is a batch process, so small quantities may be expensive but in OEM quantities, the process can be quite economical. Please call us for pricing on Avian-EP Black.
