• Eyes in the Skies- Optical Filters for Earth Observation

    “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.”

  • Optical Filters for Sensors and Detectors

    Clear the Air: New Optical Filters for Sensors and Detectors Environmental air quality; proximity control; crowd counting; climate change; the “Internet of Things”.  Our world has become an increasingly monitored place where the proliferation of sensors and detectors allows us, and our devices, to better understand and interact with our environments.  Photonics is one of […]

  • Large Format Narrow Bandpass Filters – A Uniformity Challenge

    1       Introduction Large format (>100 mm diameter), narrow bandpass filters (NBPF) are required in many fields. Applications requiring a large field of view drive the need for large collection optics, however high wavelength selectivity provided by narrow, flat-top bandpass optical filtering is also required to facilitate specific and selective analysis of a phenomena or substance […]

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.

  • Reliability as per MIL-C-48497A
  • RoHS compliant
