Technical progress of optical parts processing at home and abroad

Internationally, optical processing has developed to the fifth-generation numerical control processing technology, which has achieved high precision, high speed, efficiency and specialization. It has been able to complete the processing of high-precision aspherical parts. Among them, the German optical processing technology is more prominent.

Application range of optical parts super processing technology

At present, the materials that can be directly processed to meet the optical surface quality requirements using diamond turning technology are mainly non-ferrous metals, germanium, plastics, and infrared optical crystals. However, the processing of glass cannot meet the optical surface quality requirements and needs to continue to be polished and corrected. Another main application of CNC single-point diamond processing technology is to process various molds required for compression molding.

Explanation of these knowledge points of optical filters

The filter is used to attenuate (absorb) certain light wavebands or select a small range of light waves to pass through, while reflecting (or absorbing) other undesired wavebands. By changing the structure of the filter and the optical parameters of the film, various spectral characteristics can be obtained, so that the filter can control, adjust and change the transmission, reflection, polarization or phase state of the light wave. A common feature of filters is that there is no filter to make the image of celestial objects brighter, because all filters absorb certain wavelengths, which makes the object darker. The filter is made of plastic or glass and added with special dyes. The red filter can only let red light pass through, and so on.

Classification and explanation of filter products

There are many types of optical glass, and a filter is one of them, which can change the direction of light propagation. Optical filters are widely used in lenses, prisms, etc. of optical instruments. The filter meets the requirements of light imaging, so the quality of the filter is very high.
