    3. the application:

    3400nm infrared bandpass filter, mainly used for automobile exhaust gas detection, improving signal-to-noise ratio.

    Gas detection is closely related to human life, such as: monitoring of combustible gases in petrochemical plants, gas stations, oil depots, etc.; monitoring of automobile exhaust, industrial waste gas, urban haze; and monitoring of leakage and explosion of domestic gas and natural gas; Detection of residual concentrations of toxic gases (benzene and formaldehyde) after decoration, etc. From industrial to civilian use, gas detectors are not used for the detection of various combustible and toxic gases. KINGKI optical filters escort human safety with high performance and quality.


    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, 33 national authorized patents, and nine scientific and technological achievements 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, quality and cheap, prompt delivery.

    The simplest form of antireflection coating is a single layer. Consider Figure 4.1. Here we have a vector diagram, which, since two interfaces are involved contains two vectors, each representing the amplitude reflection coefficient at an interface.

    If the incident medium is air, then, provided the index of the film is lower than the index of the substrate, the reflection coefficient at each interface will be negative, denoting a phase change of 180°. The resultant locus is a circle with a minimum at the wavelength for which the phase thickness of the layer is 90°, that is, a quarter-wave optical thickness, when the two vectors are completely opposed. Complete cancellation at this wavelength
