Bandpass Interference Filters UV 25.4mm
Description
Essentially a stack of Fabry-Perot cavities, these filters select the transmitted spectrum by constructive and destructive interference at the boundaries between high and low index dielectric layers. Several cavities may be combined to produce a sharper cut-off and to alter the shape of the passband. Two three and four cavity designs are commonly used in these filters according to the specifications required. Absorbing and reflecting layers are also included in the stack to block the transmission of unwanted wavelengths over a wide spectrum from near UV to far IR. When selecting a filter always be certain to consider the spectral characteristics of the source and detector in use. These should be combined with the filter curve to obtain the resulting spectral response of the system.
