2050nm narrow band filter

2050nm narrow-band filter is widely used in many fields, such as infrared identification, water quality detection, infrared induction system, flame observation filter and so on. 2050nm band is a newly emerging band using narrow-band filter in the infrared band. At present, many technology companies will give priority to 2050nm or 1550nm as the first choice in developing infrared filter solutions.
