It can be used in environments where weathering and wear may affect the coating. It is available for use in the range of 250nm to 2,500nm, with options of 18%, 50%, 80%, and 94% (at 350 to 1,200nm). Compared to conventional Spectralon targets, it is possible to produce lightweight, large, and inexpensive reflective targets. We provide coated metal or glass substrates in sizes and shapes tailored to your requirements, offered as reflective targets by Labsphere.
