ZnSe Focus Lens Manufacturing: Process, Curvature Control, and Production Specifications
ZnSe focus lens manufacturing is the production of curved zinc selenide optics that converge a CO₂ laser beam to a precise focal point — typically inside a laser cutting head, marking system, or welding nozzle. Unlike flat windows, focus lenses have one or two curved surfaces that must hold tight tolerances on both surface figure […]
