There are more than 20 models in the QB blue-green colored glass series. Different models have different colors. Some models have very similar colors. The color should not be used as the basis for selection. Instead, the appropriate model should be selected based on the actual practical band to be transmitted. Models QB18, QB21, QB38, etc. will become moldy if exposed to humid air for a long time due to the composition of the materials. Therefore, this type of filter should be stored in a dry environment on a daily basis.
