Product Description

8-12um AR/AR, AR/DLC Germanium Optical Windows For C02 Laser Cavities

Germanium windows are ideal for IR applications at a broad range of wavelengths, including use in lower power CO2 lasers. Germanium also has low dispersion, ideal for imaging applications. The windows feature an AR coating providing high transmission from 3 to 12 µm.

  • Ideal for near-IR applications
  • Broadband 3 to 12 µm anti-reflection coating
  • Ideal for applications requiring low dispersion
  • Great for low power CO2 laser applications
  • Coating:antireflective coating, AR/AR coating at 10.6um, AR/AR or AR/DLC coating at 7-14um or 8-12um

Germanium Optical Properties

Germanium Optical Windows have good transmittance from 2 to 16 µm uncoated, and very low peak absorption, making the material an excellent candidate for use in C02 laser cavities. Germanium also has high opacity across the entire visible spectrum, making the windows ideal for applications where transmission of IR wavelengths only is desired.
