China Industrial Optical Window
What Is Optical Window
The optical window is used as a protective element between the two environments, which can isolate the possible pressure differences, corrosive gases, friction, shock, heat and cold in the two different environments. They are simple sheets, polished on both sides, flat and parallel. The optical window does not change the propagation characteristics of light. Generally, depending on the use environment, the optical window has different requirements in different frequency bands such as visible light, infrared, ultraviolet, etc. Of course, the best glass type is based on your needs. With knowledge, expertise and technology, OPTIC-WELL can meet your precise machining specifications in BK7, fused silica, sapphire, quartz and silicon materials. Our optical raw materials are provided by well-known manufacturers, which ensure the performance and quality of optical glass.
