SirZ 153 SWIR 150-500mm Continuous Zoom Lens

SirZ Series, Suitable for 0.9 – 1.7μm Detectors (SWIR)


• Extended range SWIR band allows for imagery in degraded visual environments

• 500 mm Telephoto narrow FOV for 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, purchase or through common communication protocols
