Optics
High Reflector Dielectric Coatings for 1 µm
Bring the capabilities of diamond-turning technology for making complex-shaped mirrors to near-infrared, high-power fiber, and direct diode laser delivery systems.
These optics mate the features of diamond-turned metal mirrors -- internal water-cooling channels, freeform surfaces, and even deformable (variable radius) surfaces -- with high-reflectance, high laser damage threshold, and all-dielectric coatings.
