The aim of this work was an investigation of surface microroughness and shape accuracy achieved on aspheric lens by subaperture (CNC) polishing. Different optical substrates were polished (OHARA S-LAH 58, SF4, ZERODUR) using POLITEXTM polishing pad, synthetic pitch and natural optical pitch. Surface roughness was measured by light interferometer. The best results were achieved on S-LAH58 glass and ZERODURTM using natural optical pitch. In the case of SF4 glass natural optical pitch showed a tendency to scratch the surface. Experiments also indicated a problem in surface form deterioration when using natural optical SGS Project No. 21066/115 at the Technical University of Liberec (Matoušek)
