This lens is widely used in Senba SMD series pyroelectric infrared sensor, human body switch, alarm infrared thermometer and infrared imaging. It can provide users with different induction angles, one is the focusing effect, the other is to divide the detection area into bright and dark areas, so that the moving objects entering the detection area can generate changing thermoluminescent infrared signals on the PIR(passive infrared detector) in the form of temperature changes.
