Introduction: infrared induction Fresnel lens is widely used in the human body induction switch, alarm, infrared thermometer and infrared imaging and other aspects. Yu Ying can provide 

Fresnel lens for customers with different induction angle, induction distance, size and test ratio. The infrared induction lens effect is as follows:

1, Collect infrared as much as possible for the sensor, improving its sensitivity

2, Expand the sensor’s induction angle.

3, The material has the filtering function, which can prevent the visible light and the infrared light from outside, except the human body’s , and enhance the anti - jamming ability.
