Product description
Band-pass filter glass is abbreviated as band-pass glass. It is a kind of glass with relatively narrow bandwidth and obvious cutoff of short-wave and long-wave, as shown in the figure. Their spectral characteristics are represented by the maximum transmittance (TM) and its wavelength (λM) position, short-wave cut-off wavelength, long-wave cut-off wavelength, and half-width. The difference between the wavelengths λ1 and λ2 (λ1-λ1) nm corresponding to half of the maximum transmittance of the band-pass glass is called half-width. The short-wave cutoff wavelength is the wavelength on the short-wave side of the peak with a transmittance equal to zero. The long-wavelength cut-off glass length is the wavelength at the peak long-wave side and the transmittance is equal to zero. In some varieties, the transmittance of the glass on the long-wave side cannot reach zero, which is expressed as the transmittance of a certain wavelength.
 
Bandpass glass is named after the first letter DTB of Chinese Pinyin, and the wavelength position value of the maximum transmittance is taken as their serial number.
