IR Lens

Infrared devices realize target detection and identification by capturing intrinsic radiant flux emitted from objects, and are widely applied in military applications. Its leading-edge fields include infrared tracking & homing guidance, passive infrared night vision as well as infrared remote sensing.
This objective adopts a motorized zoom structure to deliver stable resolution throughout the entire zoom range; its spectral transmittance for MWIR and LWIR bands exceeds 80%, with an operating temperature span of -40℃ ~ 80℃.
