Optical high precision double sided polishing to ensure that the parallelism is higher than 30 inch and high flatness 1/4λ; to ensure that IT does not affect the image quality

• Precision double sided optical coating; non two piece glue ;To effectively improve the transmittance and cut off depth
• Ion source assisted coating technology (IAD), to improve the density of the film to ensure that the filter wavelength minimizes the impact of temperature caused by the temperature drift
• High uniformity planetary wheel coating fixture to improve the uniformity of the filter wavelength
• Optical equipment professional fine sandblasted and anode treatment to prevent reflection

•
