B+W 65-011796 77mm UV Black Filter

B&W 77mm UV Black (403) Filter - This filter should not be confused with a traditional UV filter. This specialized filter is opaque to the eye and passes UV A radiation from 320-385nm. It also blocks all visible light. When used with the appropriately sensitized film it is especially effective when used in forensics or in certain flourescent photography. The filter ring is made from brass yielding a stronger product. Brass filter rings are also less prone to jamming.
