Mid IR
Iridian’s SWIR, MWIR and LWIR bandpass filters are designed to optimize detection of spectral emission lines.
Spectroscopic Filters
Broadly speaking, these filters are used in optical systems based on Raman spectroscopy or laser-induced fluorescence.
Telecom Filters
Iridian offers high quality telecom filters at competitive prices to meet the ever increasing wireless and fiber-to-the-home traffic demand.
Fluorescence Filter Sets
Iridian’s single band fluorescence bandpass filter sets have been optimized for use in a variety of fluorescence instruments.
Multi-Zone Filters (MZF)
Iridian offers both assembled multi-zone filter arrays and patterned multi-zone optical filters to address these growing needs.
3D Cinema Optical Filters
Iridian has manufactured millions of pairs of re-usable 3D color band glasses over the past five years.

The Eyes Of The Instruments: Using Optical Filters To Observe And Measure Earth From A Different Perspective
“Measurement is the first step that leads to control and eventually to improvement. If you can’t measure something, you can’t understand it. If you can’t understand it, you can’t control it. If you can’t control it, you can’t improve it.” H. James Harrington Since...
