Fused-Silica Aspheres for 1 µm Lasers
Achieve diffraction-limited focused performance while also minimizing total component count in beam delivery systems for direct-diode, fiber, and disk lasers.
Fused-silica aspheres offer an excellent balance between performance and cost in beam delivery systems for visible and near-infrared lasers with powers of over 1 kW.
Fused-Silica Aspheres Capabilities
Specify high-precision polished fused-silica aspheres of up to 200 millimeters in diameter.
