The HIR22-750 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 22-750mm focal length the HIR22-750 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.

  • Thermal Focus Compensation System "TCS" Option:
  • Zoom Lenses Using ED Glass or SD Glass (SD is a Better Material than ED) has Back-Focus Shifting Problem by Temperature Due to Thermal Expansion of the Lens Itself and Mechanical Parts.
  • The Thermal Focus Compensation System Monitors the Lens and Body Temperature with a Micro Processor and Automatically Adjusts the Back-Focus Correctly Depending on Lens Body Temperature. 
  • There is No Need to Refocus During Temperature Change. 
  • Selectable Filter System "SFS" Option: Internal Selectable Haze Cut Filter Used to Better View Through Hazy Locations. Other Selectable Filter Options Available)
  • Serial Communication Control "SCC" Option: RS-232C or RS-485 Communication For Lens Control
  • Auto-Focus Option Available
  • Auto-Iris Manual Override Option Available
