China Infrared Optical Filter Glass has a clear imaging effect
However, because the film forming temperature is above 150 degrees, the SIO2 stress is large, and the lens is required to be around 0.21 mm, the deformation of the film is large, resulting in a very large difference in uniformity between different filters, which exceeds the spectral specification requirements and reduces the Product availability. China Infrared Optical Filter Glass requires a light-transmitting area. The higher the transmission, the clearer the image and the higher the sensitivity. The existing technology has a limited refractive index of about 3.5 due to the obtained SIH layer, and the cut-off, bandwidth stability and low transmittance , the average value often fails to meet the requirements, and the cut-off OD value is low.

The traditional method of obtaining material layers is to sputter material molecules from the target to form a thin film on the substrate, and then turn to RF or PBS to fill different reactive gases to form plasma and combine with the thin film on the substrate to form a new material layer. .
china Infrared Optical Filter Glass allows optical signals to pass through in a specific wavelength band, while the optical signals on both sides that deviate from this band are blocked. The passband is relatively narrow, generally less than 5% of the central wavelength value, and is often used in fluorescence analysis. instrument, infrared camera, rangefinder, etc.
