Details

The λ/4K9 visible light window plate is a parallel planar plate commonly used as a protective window for electronic sensors or detectors of external environments.
This product provides protection for electronic devices/sensors without changing the magnification of the optical system. The standard surface accuracy of this product is λ/4, which can minimize the occurrence of beam distortion and scattering. The design of double-sided broadband anti reflective film provided by Guangtan Intelligence also greatly reduces the interference of ghost images.
Guangtan Intelligent provides flat windows on K9 substrates without coating or coated with anti reflective film. The options for anti reflective films include VIS (350-700nm), NIR (600-1100nm), and SWIR (900-1700nm).
Guangtan Intelligent has complete manufacturing and testing equipment, which can provide you with high-quality optical components. We are a professional optical component supplier in China. We can customize window panels that meet your usage requirements according to your needs. If you have any questions or requirements, please feel free to contact us and we will be happy to serve you.
