PIR infrared Fresnel lens

Product Overview

Aubor The infrared laser Fresnel lens developed is suitable for laser receiving end or emitting end, especially for PIR + laser hybrid module, ToF ranging module, infrared communication system, active optical lighting equipment. Through the special structure of the Fresnel surface design, the lens can effectively realize the directional control goals of infrared laser collimation, beam expansion, diffusion, limited angle output, etc.

We provide one-stop customized services from wavelength adaptation, FOV angle calculation, material coating selection, to structural packaging adaptation to meet the needs of high-precision scenes.

Why choose Aubor?

Infrared laser is not "visible light for a wavelength", it requires extremely high wavelength accuracy + beam of light molding control. The solution provided by

Aubor has the following characteristics:

supports 1550nm band material selection and coating adaptation, specially optimized for security high-power scenarios

Fresnel structure supports light simulation verification, FOV error control 3

CNC + high-precision mold to make Fresnel steps, surface profile accuracy is better than 2μm

can cooperate with customer laser module structure packaging, support card slot/gluing/ultrasonic welding and other processes docking

Customer case A security radar customer in the United States: using 940nm Fresnel lens for laser beam expansion, improving detection coverage by 25% at the same power

A South Korean ToF manufacturer: Customized laser collimating lens, effectively reducing the receiving end error by 1.5%, through product certification for elevator induction
