Filters

Precision optical filters since 1969, from UV to NIR. We specialize in custom filters from prototype to OEM quantities. Fluorescence, astronomy, and overrun filters in stock. Prototyping, engineering, and high-volume production utilizing plasma-assisted reactive magnetron sputtering, e-beam, thermal evaporation, and ion assist. ISO 9001:2015 Certified.

Designer and manufacturer of interference filters: narrow and broad bandpass, long- and shortwave, ND filters, atmospheric windows, AR and metallic coatings. Holographic diffraction gratings: plano, concave and blazed, pulse compression/stretcher gratings. WDM and telecom applications include diode laser tuning gratings and network communications gratings.

Iridian Spectral Technologies, an IDEX Optical Technologies company, provides custom, wavelength selective optical filter solutions for communications (telecom, datacom, lasercom/satcom), spectroscopy (Raman, fluorescence), remote sensing (EO, lidar), and more applications. Our optical filters cover the spectral range from UV 300 nm to LWIR 15 microns.
