    3. the application:

    2190nm food infrared bandpass filter, mainly used for food testing equipment.

    Infrared spectroscopy is one of the fastest growing high-tech analytical techniques in the past 20 years. In the 1980s, China began to research and apply near-infrared spectroscopy. In the late 1990s, it was gradually applied in food, agriculture, petrochemical, pharmaceutical, food and other fields in the industrial chain, and gradually played a role in food production and scientific research. More and more important.

    An effective coating is one consisting of two quarter-wave layers (see Figure 4.10). The appearance of the vector diagram at three different wave- lengths is shown in (a), (b) and (c). Atλ= (3/4)λ0 and λ= (3/2)λ0, the three vectors in the triangle are inclined at 60° to each other. Provided the vectors
