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.

Iridian’s superior color filters provide:

  • Steep edges (cut-offs down to 40 cm-1)
  • High transmission (> 94%) and high blocking (> OD3)
  • Optimized for use with various LED sources
  • Various threaded mount size available M25.5 – M62.0
  • Other color wavelengths and bandwidths available
