Bandpass Filter, Optical Glass

Edit:Shanghai TaiYang Technology Co.,Ltd      Date:Mar 03, 2017

Filter, Glass Filter, Optical Lens manufacturer / supplier in China, offering Bandpass Filter, Optical Glass, Neutral Density Optical Glass, Optical Filter, Camera Filter, Blue Glass, Optical Glass, and so on.

This kind of glass only transmits the light within a narrow wavelength range as shown in figure. Its spectral characteristic is composed of maximum transmissivity (TM) wavelength of the peak (lM), front-cut-off wavelength, behind-cut-off wavelength, and half-peak width.

The wavelength corresponding to the half of the maximum transmissivity are l2 and l1. And the half-peak width is determined by l2 - l1. Front (behind)-cut-off wavelength is corresponding to the wavelength of "zero" transmissivity. But there are a few types which transmissivities of the behind-cut-off wavelengthes can't approach to zero, then they are determined by the transmissivity of the certain wavelength. 

Band-pass filter glass is named DTB, and wavelength of the peak is used as its serial number.
