Imaging Filters

Iridian Spectral Technologies Ltd designs and manufactures a range of dielectric optical filters for machine vision and imaging applications. Iridian’s Imaging Filters pass specific UV, visible, or IR wavelengths while providing superior blocking of unwanted light. These filters with greater durability for longer lifetimes can be used to improve image contrast and isolate spectral regions and colors.

Mid IR Bandpass Filters

Iridian’s SWIR, MWIR and LWIR bandpass filters are designed to optimize detection of spectral emission lines.

These filters are deposited using energetic sputtering, which makes them very hard and durable. The resulting filters also have exceptionally high transmittance levels and blocking from the visible to the LWIR. Iridian has off-the-shelf band pass filters for many of the wavelengths commonly used for gas detection.
