The short-wave pass filter is a cut-off filter in the interference filter. The cut-off filter is divided into a long-wave pass filter and a short-wave pass filter, that is, a certain wavelength range of light beam transmission is required to deviate from this The wavelength of the light beam changes to cut-off. Usually we call the filter that reflects (cuts off) the short-wave region and transmits the long-wave region as a long-wave pass filter. On the contrary, the short-wave direction is transparent, and the long-wave direction is cut-off to isolate The effect of long wave is called short wave pass filter.
