Description
Color Filters are named based on the average transmissivity characteristics in 400nm to 700nm wavelength with 2mm thick. Sample is 70%, then it's named as ZAB70. And there are ten types of glasses in this part. But three types of them(ZAB65,ZAB30,ZAB5)are tested in 440nm-660nm wavelength.
