MIRZ 2021 MWIR 20-420MM (X21) F/5.5 CONTINUOUS ZOOM LENS

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
  • Athena™ 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
