MIRZ 1522 MWIR 15-330mm (X22) F/4 Continuous Zoom Lens

Key Features:

  • Fits the space claim of the popularized 15-300mm f/4 packages while delivering 10% more in range – 330mm in Narrow FOV
  • Recognition of small targets at ranges up to 8km makes this lens ideal for medium range IR applications
  • 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
  • First x22 f/4 lens on the market
