          The 650nm narrow band pass filter is in fact the band pass filter, in order to cope with the vast number of users interests and renamed as. The majority of users, especially the laser measurement of stray light, range finder user requirements and is not too high, so long as can filter out 85% of the light is enough, therefore it is suitable for semiconductor laser, does not participate in the imaging apparatus and equipment and custom. Also according to the special needs of customers are glued or applied anodic aluminum sleeve for special purpose.

          Optical indicator:

          The center wavelength: 650 ± 2nm

          Transmittance: T>91%

          Bandwidth: 40nm

          Stop band 400nm-620nm

          680nm-1100nm

          The cutoff rate: T<0.1%

          Product features:
