IR Transmitting Glass

Chalcogenide Glass FI-02

Our unique chalcogenide glass is free from hazardous substances like arsenic and selenium. It has excellent infrared transmittance and is available from prototyping to mass production with our in-house production.

Features

  • High infrared transmittance in sensitive wavelength ranges
  • Free from hazardous substances (arsenic, selenium, etc.)
  • High refractive index/low dispersion (for aberration suppression)
  • Flexibility from small batch to mass production
  • Large aperture sizes available (up to Φ300 mm)
