HIGH PERFORMANCE FILTERS TO SUPPORT THE BROADEST RANGE OF APPLICATIONS

We design and manufacture optical filters in a broad wavelength range from ultra violet to the far infrared to meet the unique requirements of diverse markets including: space, astronomy, defense, thermal imaging, medical instrumentation, 3D sensing, gas & flame detection, process control, semiconductor and automotive sensing & display.

SPACE/DEFENSE

Whether terrestrial, astronomical, space-based or defense applications, we have the right filter for you. We manufacture high performance filters that enable LIDAR systems as well as filters for imaging & instrumentation on major telescopes.

Astronomical Filter Advantages

  • Ultra narrow bandpass filters exhibit superior discrimination
  • Capability to coat large filters up to 30 inches in diameter
  • Rugged and resistant to external ground & space environments
  • Spectrally stable elements made to exacting tolerances
  • High reflectance mirrors with very low polarization
  • Coatings for deformable mirrors
  • Solar suppression minimizes system thermal loads

IMAGING

We offer optical interference filters and thermal imaging filters for applications supporting diverse industries: medical, chemical, biotechnology, environmental, fluorescence imaging, commercial, industrial and more.

Raman and Fluorescence Filter Advantages

  • Optical interference filters provide exceptional image contrast
  • Fluorescent filters that perform consistently from ultraviolet through near infrared
  • Long life spans for science, medical and analytical uses

Thermal Imaging Filter Advantages

  • High signal-to-noise ratio for less noise and enhanced thermal image
