Product Family Description

  • Laser Damage Threshold >10 J/cm2 @ 2µm, 10ns, 10Hz
  • Designed for Holmium and Thulium Laser Sources
  • λ/7 Surface Accuracy

TECHSPEC® 2µm Laser Mirrors are designed for use with Holmium (2100nm) and Thulium (1940nm) doped laser systems. These mirrors are ideal for medical, industrial, and metrology application spaces. The 2 micron wavelength regime is useful for surgical procedures as it can target discrete depth levels of tissue beneath the skin’s surface. TECHSPEC® 2µm Laser Mirrors feature guaranteed laser damage thresholds >10 J/cm2 and >99% reflectivity at 2 microns.

Note: For more information on 2µm laser source applications, please see the Characteristics of 2µm Lasers.
