12.7mm 45°, 2μm Laser Line Mirror

Product Details Laser Damage Threshold >10 J/cm 2 @ 2µm, 10ns, 10Hz Designed for Holmium and Thulium Laser Sources λ/7 Surface Accuracy TECHSPEC High Performance 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 High Performance 2µm Laser Mirrors feature guaranteed laser damage thresholds >10 J/cm 2 and >99% reflectivity at 2 microns. Note: For more information on 2µm laser source applications, please see the Characteristics of 2µm Lasers .
