Silicon Wedge Windows

silicon wedge windows has good transmittance performance in the 1-7 μ m wavelength range, and it also has good transmittance performance in the far-infrared wavelength range of 30-300 μ m. A design with a wedge-shaped shape. Used to separate the environment on both sides and change the deflection path of light. It has high transmittance in both visible and infrared bands, as well as low reflectivity and low absorption. Silicon wedge angle pieces come in various sizes and specifications to meet different application requirements. Can be coated with reflective film, anti reflective film, filter film, spectroscopic film, polarizing film, and metallization film systems.
