A window or a diffuser
A window is a parallel plane plate, usually used as a protective film for an electronic sensor or a detector in the external environment. When choosing a window, the user should consider whether the transmission properties of the material and the mechanical properties of the substrate are consistent with the application requirements. The window film does not change the magnification of the system. We provide window films on various substrates, including silicon germanium (Ge), (Si), N-BK7, UV, ZnSe fused silica (ZnSe) or potassium bromide (KBr). Many of our optional antireflection films can be used in ultraviolet light, visible light, or infrared spectroscopy.
The diffuser can be used to control the area of illumination diffusion, and the light source is diffused evenly when the light is spread through the diffusion sheet. Our products include holographic diffuser, milk diffuser or glass diffuser with various sizes or diffusion angles available. Compared with the glass diffuser, the holographic diffuser can bring excellent transmittance. The diffusion plate or the wool glass diffuser is a low cost substitute.
