Aspherical Spherical Lenses
Generating an aspheric departure on a spherical substrate requires a stable removal function and a tight interferometric feedback loop. Our strength here is the ultra-smooth finish — surface roughness better than 0.3 nm RMS — which keeps scatter loss low in high-power or short-wavelength beam paths.
