Custom Scientific UBVRI filters have been used in institutions and observatories around the world such as Kitt Peak, Mauna Kea, and the CTIO/Chile.

These filters provide a natural color reproduction of planets, stars, emission- and reflection nebulas.

UVBRI filters have been the standard for photometric measurements for decades.  They have evolved over time as technology changed.  H. Johnson in the 1950s and A.W.J. Cousins in the 1970s designed these filters for photomultiplier tubes (PMT).
