Iridian offers a full range of multiple band pass filters in the visible and near IR wavelength ranging from 400nm-2500nm. These filters manage bandpass regions with blocking to OD6 ( 60dB), transmittance >90% and operating angles from 0 to 45 degrees. These filters have 2, 3 or even 4 bandpass regions defined according to the customer application.
Iridian Multiple Band Pass Filters Advantage:
All of Iridian's filters use the same hard sputter coatings for maximum transmission, steep transitions from blocking regions to full transmission and exceptional blocking in the blocking bands.
Custom Multiple Band Pass Filters
In addition to the standard Multiple Band Pass Filters above, Iridian can custom-manufacture these filters to your specifications.
