The Graflex NITE☆TEL Catadioptric Fixed Focal Length Lenses open up a new dimension in day and low light level long range video surveillance and tracking applications. These compact, lightweight, rugged, nitrogen purged zoom lenses are enclosed in an aluminum housing making it suitable for both mobile and stationary applications.

The NITE☆TEL catadioptric FFL lens offers the following features:

  • High resolution, contrast, MTF, and transmission (visible through near IR) 
  • Provides long range low light level capability and ultra long range viewing during daylight conditions.
  • Motorized and optionally RS controlled ND filters for light attenuation (Standard = ND, Clear, and Visible Blocking)
  • Options include temperature and purge pressure feedback & control.
  • Aperture suitable for low light applications
  • Enclosure includes mechanical interface for mounting a “spotter” such as our 28X motorized zoom lens.
