Objective lenses for gobos and slide projection lighting fixtures have been introduced by Docter Optics Inc. The lenses are available in three-, four- or six-element designs with fixed or variable focal lengths from 45 to 500 mm. Features include speeds from f/1.7 to f/5.6 and operating wavelengths from 400 to 700 nm. The lenses' air-to-glass surfaces are antireflection-coated for high light transmission, and they are mounted in compact housings of metal or plastic.
