Main Factors Affecting the Performance of Infrared Optical Filter Glass china
The drift of Infrared Optical Filter Glass china with changes in ambient temperature can be attributed to the temperature coefficient of refractive index of the film material and its thermal expansion coefficient. The optical properties of Infrared Optical Filter Glass china are sensitive to temperature changes. For materials with a positive temperature coefficient, when the temperature change is small, the main effect is that the wave peak moves to the long wave direction as the temperature rises; when the temperature changes greatly, the moisture in the filter will usually be released, which may cause The crest moves towards the shortwave direction.
Analyze the relationship between its optical properties and factors such as aggregation density, temperature change and moisture absorption. According to the thickness error of each layer of the filter film caused by moisture absorption and temperature, the models of spectral drift before and after moisture absorption and before and after temperature change are given. Through the analysis and preliminary experiments on the optical stability of Infrared Optical Filter Glass china, the measures to improve the optical performance of the narrow-band filter are proposed.
After Infrared Optical Filter Glass china is exposed to the air, it will soon appear macroscopic water absorption. First, many water-absorbing spots appear on the surface of the film layer, and then gradually expand and connect into one piece, and finally form a uniform water-absorbing layer. After the water absorption of the film reaches stability, measure the transmittance of the filter, and it will be found that not only the peak wavelength shifts to the long wave, but also the transmittance of the peak wavelength increases.
