Super Polished
Laser-chemical fabrication is completely non-contact. The method produces no scratches, digs, or subsurface damage.
Our optics have best-in-class surface roughness, whether we're talking flats, aspheres, or even freeforms. That's right. Super-polished freeforms.
We've demonstrated exceptional quality using white-light interferometry, laser scanning confocal microscopy, and atomic force microscopy (AFM). Fused silica (Corning 7980) has surface roughness as low as 0.25nm RMS. Other glasses such as N-BK7 (Schott), and newly demonstrated, high index, Lanthanum Fluorides also exhibit this same low roughness.
