Supplier: Thorlabs, Inc.
Description: is the limiting factor rather than the diffraction limit. Because the aspheric lenses are corrected to eliminate the spherical aberration, only diffraction limits the size of the focal spot. For focusing applications, the lens should be oriented so that the side with less curvature faces the source.

Saint-Gobain Surface Conditioning Group
Ophthalmic Market, Polishing Lens Compounds
Saint-Gobain Ceramic Materials' Specialty Abrasives group has launched a new line of plastic lens polishing compounds for the ophthalmic industry to polish MR lens, polyurethane lens and polycarbonate lens. Our patented plastic lens slurries were first proven to be effective on conventional polishing machines that rotated in symmetrical and spherical motion until the desired optical surfaces were achieved. We have also developed a line of polishing compounds suitable for Freeform optical... (read more)
