Abstract

The invention belongs to the solar energy industry field, especially relates to a Fresnel lens detection device. The Fresnel lens detection device comprises a system adjustment control unit, a vertical rotation unit, a bracket, a horizontal rotation unit, and a detection unit. The system adjustment control unit, the vertical rotation unit, the horizontal rotation unit, and the detection unit are disposed on the bracket. The system adjustment control unit is respectively connected with the vertical rotation unit and the horizontal rotation unit. The vertical rotation unit is used to control the moving of the detection unit in the vertical direction, and the horizontal rotation unit is used to control the moving of the detection unit is the horizontal direction. The technical defect of the prior art of the lack of the Fresnel lens detection device capable of solving the abnormal working problem of the Fresnel lens during the use is overcome.

Description

technical field [0001] The invention belongs to the field of solar energy industry, and in particular relates to a Fresnel lens detection device. Background technique [0002] Fresnel lens, also known as threaded lens, is mostly a thin sheet made of polyolefin material, and also made of glass. One side of the lens surface is smooth, and the other side is engraved with concentric circles from small to large. , its texture is designed according to the interference and interference of light and the requirements of relative sensitivity and receiving angle. Lens requirements are high. A high-quality lens must have a smooth surface and clear texture. Its thickness varies with the application, mostly around 1mm. It is characterized by large area, thin thickness and long detection distance. Fresnel lenses are often equivalent to convex lenses for infrared and visible light, and the effect is better, but the cost is much lower than ordinary convex lenses. It is mostly used in occa...
