    3.the application:

    1310nm ice and snow infrared bandpass filter, mainly used for highways, railways and other ice and snow detection instruments.

    The detection of ice and snow on highways and railways mainly diagnoses whether there are ice, snow, frost, etc. on the road surface; the snow depth detector measures the depth of snow accumulation.

    Kingki's ice and infrared detection infrared filter is the core component of the instrument.


    4.the company's strength

    Kingki has long been responsible for the research and production of military optical coatings. The chief engineer has more than 40 years of military optical coating experience, and has 33 national authorized patents. Nine optical film systems have won the People's Republic of China Science and Technology Progress Award.

    Kingki has a high-end factory building of 4,000 square meters, 13 sets of advanced coating machines and complete test equipment, with the ability to mass produce high-end optical filters.

    Kingki's wide range of products, excellent performance, high quality and low price, prompt delivery

    It is relatively easy to extend the vector method to deal with four layers, where the zeros of reflectance are found at (5/8)λ0, (5/6)λ0, (5/4)λ0, and (5/2)λ0, an even broader region than the three-layer coating. Five layers are equally straightfor- ward. Whether such coatings are of practical value depends very much on the application. For many purposes, the two-layer coating is quite adequate.

    The addition of an extra layer makes the exact theory of the three-layer coating very much more involved than that of the two-layer coating. The number of possible groups of designs is enormous. It therefore becomes profitable to use techniques that, rather than calculate performance in detail, simply indicate arrangements that are likely to be capable of acceptable per- formance and eliminate those that are not. Performance can then be accu- rately calculated by the procedures of Chapter 2.
