Sapphire Aspheres for High-Power 1 µm Lasers
Improve cutting performance and reduce downtime of high-power, 1 µm laser cutting and welding systems with these diffraction-limited focusing optics.
Sapphire lenses handle higher powers, have lower focal shifts, and experience less contamination effects than other materials. The high refractive index of sapphire enables smaller, lighter designs with fewer lenses lowering system operating costs.
Sapphire Aspheres Capabilities
Specify high-precision polished sapphire aspheres of up to 100 millimeters in diameter.
