How to understand the bandwidth of the Bandpass Optical Filters

May 06,2022

SIZE

The two wavelengths in a Bandpass Optical Filters whose transmittance is equal to 50% of the peak transmittance are called half-power wavelengths. The bandwidth of a filter is the difference between half-power wavelengths, called the full width at half maximum (FWHM). A filter defines a center wavelength band shape by calculating the average of two half-power wavelengths, usually defined as a multiple of BW or FWHM, and it defines the rate of attenuation relative to the change in wavelength along the slope of the bandpass.

Bandpass Optical Filters

Bandpass type: The light in the selected band passes through, and the light outside the passband is cut off. Its optical indicators are mainly the central wavelength (CWL) and the half bandwidth (FWHM), which are divided into narrowband and broadband, such as narrowband filters and Bandpass Optical Filters. light sheet.
