DETAILS
NBP850nm narrow bandpass filter
850nm black glass filter is a filter product with high cut-off depth requirements among black glass optical colored glass materials. It can cut off deeper in the cut-off optical band and filter more interference light, so as to achieve a perfect cut-off between OD2-OD6.
