SirZ 500 SWIR 150-500mm Continuous Zoom Lens

Key Features :

  • Extended range SWIR band allows for imagery in degraded visual environments
  • 500 mm Telephoto narrow FOV for more pixels on target
  • Motorized Continuous Zoom allows you to zoom while keeping the imagery sharp
  • The lens controller auto compensates thermal deviations and keeps the imagery crisp within a wide temperature range
  • Athena™ programmable DSP controller gives you the freedom to set targets and to calibrate the lens for different field conditions
  • Operate and calibrate the lens with our simple and friendly GUI, purchase or through common communication protocols
