RGB MODULAR LENSES FAMILY F/N=4
General Description
This RGB lenses, designed for a three-CCD color camera, are ruggedized for industrial and field applications. Chromatically corrected under 6mm, them compensate for dichroic aberration, distortion and vignetting.
Characterized by a medium focal length value, a long back focal length, and high resolution, these lenses can be used with both linear and matrix three-CCD cameras.
