Infrared (IR) Domes

Name: Infrared (IR) Domes
Brand: Shenzhen Solar Valley Scitech Development Co., Ltd.

Infrared (IR) Domes use a CNC high precision machines, grinding high precision spherical domes to meet quality requirements under the condition of precise control of the machine tool and processing environment. The spherical surface is polished to an optical mirror using high precision correction polishing technology, so that the parallelism of the convex surface with respect to the concave surface is less than 0.002mm, ensuring that the image and light propagation characteristics are not distorted.
