Low Light

Navitar carries three "high speed" CCTV Lenses, 17, 25, and 50mm f/0.95. These are 1" format lenses and are used primarily when light collection is at a premium (high speed cameras, fast moving objects, low level fluorescence).

The lenses are designed for imaging at significant distances, with relatively low magnification. Because of the steep ray angles dictated by the high f numbers, the image at lower working distances (higher magnification) is soft due to spherical aberration and far field performance suffers. Still, many of these lenses are used with reduced format cameras and auxiliary vision enhancement systems.
