MirZ 1075 MWIR 40-1075mm (X29) F/5.5 Continuous Zoom Lens

Key Features:

  • Unprecedented 29X Continuous Zoom range – up to 1075mm Focal length
  • Recognition of small targets at ranges up to 20km makes this lens excellent for long range IR applications
  • Narrow Field of View (<0.55 degrees) allows 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, or through common communication protocols
