Fresnel lens (Fresnel lens), also known as threaded lens, is mostly a thin sheet made of polyolefin material. The surface of the lens is smooth on one side, and the other side is engraved with concentric circles from small to large. Its texture is designed according to the requirements of relative sensitivity and receiving angle by utilizing the interference of light. A high-quality lens features large area, thin thickness (mostly around 1mm), and long detection distance. It is much more cost-effective than ordinary convex lenses for applications such as slide projectors, infrared detectors, and sensors.
The production team consists of technical experts with years of industry experience, capable of customizing various optical components based on detailed requirements, drawings, or samples. The manufacturing process adheres to ISO9001 quality systems using advanced production and testing equipment to ensure precision for both small batch and mass production needs.
