MirZ 2021 MWIR 20-420mm (X21) F/5.5 Continuous Zoom Lens

MirZ 2021


Key  Features:

  • Compact size and recognition of small targets at ranges up to 10km makes this
    lens optimal for medium range IR applications
  • Motorized Continuous Zoom allows you to zoom while keeping the imagery sharp
  • Ideal solution for space limited environments, payloads and airborne applications
    • The lens controller auto compensates thermal deviations and keeps the imagery crisp within
    a wide temperature range

• AthenaTM 2 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
