  • 10x (8.5-85mm) Infrared Corrected Motorized Zoom Lens
  • Special Low Dispersion Glass
  • Many Options Available

  • SKU: HIR8-85M Series

The HIR8-85 lenses are powerful infrared (IR) corrected motorized zoom lenses.

The IR corrected SD Glass (special low dispersion glass) has lower chromatic abberation than ED glass (extra-low dispersion glass) which allows the lens to always stay in focus, from visible light to infrared light.

With a 8-85mm focal length the HIR8-85 can benefit almost any application.

Designed to fit a C-Mount camera with a 1/2" CCD or smaller, this can also be used on a CS-Mount camera with an additional C/CS adapter.
