Although optical windows are just two parallel surfaces and in most cases are used to protect the sensors and other electronic instruments inside the system from environmental conditions, they are absolutely indispensable and should be adapted to the needs of the entire system.
ECOPTIK provides parallel windows in a variety of materials, covering ultraviolet, visible, and infrared wavelengths, from 180nm to 2600nm.
The advantage of ECOPTIK lies in the customized processing according to customer requirements, high-precision surface flatness, strict surface quality and high parallel requirements, etc.
At the same time, ECOPTIK can also provide coating services, including AR Coating, metal reflection, dielectric high reflection, etc.
