#4B0082 BN450 Narrow Indigo Bandpass Filter

BN450 is commonly used in fluorescence applications with an emission ranging from (430-460nm), it is suitable for use in LED or laser diode applications with higher than normal ambient lighting conditions and is less sensitive to angle of incidence variations than traditional interference filters. The BN450 is an ideal filter for applications utilizing 450nm blue laser triangulation sensors.

The performance of a filter is based on what happens to light passing through the filter. The apparent color of light reflected off the surface is not a reliable way to judge the filter's capabilities. Batch-to-batch difference in the apparent color of the coatings or filter substrates can often be easily seen when looking at two examples of the same filter type. The color of the coating does not indicate a disparity in performance. Filters 62mm and greater have a surface quality tolerance of 60/40.
