Polishing or grinding method, processing method of optical element, processing method of fluorite, polishing or grinding apparatus, polishing and/or grinding apparatus for optical element, apparatus for processing surface of optical element, and lens
During grinding and polishing of an optical element made of a crystalline material such as fluorite, tarnish and a reaction with diamond polishing abrasive grains included in processing liquid are prevented. To this end, processing liquid supplied to a processing region of a surface to be processed and processing liquid supplied to a non-processing region are divided.
