Web4 feb. 2024 · UV will generate ozone from oxygen in the air and if you are creating enough of it (eg for broadband spectoscopy) then it will be essential that it is well enclosed and ventilated. For UV, specialised coatings for the optics are needed. These need careful cleaning; ensuring there is no water contamination. For blackbody radiation, ridiculous ... Web3 apr. 2024 · 2. Surface Texturing. Lasers can create textures or patterned microstructures on the surfaces of components or products that improve physical performance, such as wear rates, grip, optical properties, and load capacity. Laser micro-texturing can create roughness on medical implants that make it easier for new tissue or bone to take hold and ...
