How it works

Image contrast suffers when stray light reaches the focal plane. Even the best flat black paint reflects about 5% of the light that strikes it, and more when viewed at high angles of incidence.

In 1997, Protostar was the first to develop a black, low-pile surface for lining telescope tubes. It absorbs well over 99% of visible light, and is effective at all angles of incidence. Unlike decorative grades of flocking, Protostar light trap material doesn't shed on your optics.
