Why Fresnel lens is used in PIR Sensor? AnswersDrive
A Fresnel lens is a type of composite compact lens developed by the French physicist AugustinJean Fresnel for use in lighthouses It has been called “the invention that saved a million ships” The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design A.
