Chalcogenide Optics

Chalcogenide glass, composed of sulfur, selenium, and tellurium, offers a unique set of optical properties that make it an ideal material for a wide range of infrared applications.

With superior infrared transmission, a high refractive index, and exceptional nonlinearity, chalcogenide optics are revolutionizing the design and performance of photonic devices.

Properties of Chalcogenide Glasses

  • Wideband Infrared Transmission: Chalcogenide optics excel in transmitting infrared light across a broad spectrum, including the crucial 3-5 µm and 8-12 µm bands. This makes them invaluable for applications in thermal imaging, sensing, and spectroscopy.
  • High Refractive Index: With a higher refractive index compared to traditional materials, chalcogenide optics enable the design of compact and efficient optical systems.
    This is particularly beneficial for applications with space constraints.  
  • High Nonlinearity: Chalcogenide glass exhibits significantly higher nonlinearity than other materials, making it ideal for photonic integrated circuits and devices requiring nonlinear optical effects.  
  • Low Temperature Coefficient of Refractive Index: Chalcogenide optics demonstrate excellent stability under varying temperature conditions, ensuring consistent performance in demanding environments. This property is crucial for producing athermalized lens assemblies.
  • Reliable Machinability: Chalcogenide glass can be easily machined into various lens forms, including spherical and aspheric designs, providing flexibility for custom optical component fabrication.
