Optical Filter - Bandpass Filter

Bandpass Filters

A bandpass filter transmits a certain range of wavelengths (passband) and restricts unwanted wavelengths. These are angle-sensitive filters, so be careful while integrating them into a system. The transmission percentage of a filter can be improved by coating the surface. The bandpass filter is available in a different range of bandwidths (narrow or broad) and in different spectral (UV, VIS, NIR or IR) regions. Applications include fluorescence microscopy, spectroscopy, imaging, and many other fields.
