Schneider Fast C-Mount Lenses are designed for extremely low light situations, the high aperture (f/0.95) of these lenses provides excellent image quality even under low light conditions. The Xenon lenses are designed to cover the visible spectrum (400-700nm). Locking focus and iris prevent change in stressful environments. The front filter thread allows the use of color filters to increase contrast, for increased accuracy of sorting, picking or measuring applications, or reducing glare with polarizing filters. The Xenon 0.95/17mm C-Mount Lens covers a 2/3” format sensor with an 11mm image circle. The Xenon 0.95/25mm C-Mount Lens covers a 1” format sensor with a 16mm image circle.
