MirZ 825 MWIR 40-825mm (X22) F/4 Continuous Zoom Lens

Key Features:

  • Recognition of small targets at ranges up to 18km makes this lens ideal for long range IR applications
  • Narrow Field Of View (<0.7 degrees) allows 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
