MIRZ 4022 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
