536nm bandpass filter

A bandpass filter only allows light to pass through within a specified range. The specific structure is as follows: coating a semi transparent metal layer on a glass substrate, then coating a magnesium fluoride barrier layer, and finally coating a semi transparent metal layer. These two metal layers form a Fabry Perot standard tool with two parallel plates. When the distance between the two poles is of the same order of magnitude as the wavelength, the interference peaks of different wavelengths in the transmitted light will be very separated. By using other absorption filters, unacceptable light can be filtered out to obtain the specified bandpass filter plate. The passband of a filter is much narrower than that of a regular absorption filter. In addition, there are Fabry Perot type filters with all dielectric materials. Two typical structures are bandpass filters that can have a passband from infrared to ultraviolet as needed. In the visible area, a bandpass filter can be used to segment the image into different colors in the visible light region. In the infrared region, it is commonly used in carbon dioxide lasers, missile guidance systems, and satellite sensors.
