    3. the application:

    1477nm ice and snow infrared bandpass filter, mainly used for ice and snow detection instruments.

    The detection of highway ice and snow mainly diagnoses whether there is snow, frost, etc. on the road surface; the snow depth detector measures the depth of snow.

    Kingki's ice and infrared detection infrared filters are key components 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

    A particularly useful technique of this type has been developed by Musset and Thelen [6]. It is based on Smith's method—that is, the method of effective interfaces. We recall from Chapter 2 that this involves the breaking down of the assembly into two subsystems. These we can label a and b. The overall transmittance of the multilayer is then given by
