Products - Clear Align – custom imaging & laser systems for ISR»Lenses»MirZ - Midwave»MIRZ 4021 MWIR 40-840 MM (X21) F/5.5 CONTINUOUS ZOOM LENS

MIRZ 4021 MWIR 40-840 MM (X21) F/5.5 CONTINUOUS ZOOM LENS

Key Features:

  • Recognition for small targets at ranges up to 14km makes this lens ideal for medium range IR applications
  • Motorized Continuous Zoom allows you to zoom while keeping the imagery sharp
  • 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
