Abstract

PURPOSE: To improve polished precision of a lens and to facilitate replacement of a polishing sheet, by forming radial grooves in the flat polishing sheet, and adhering it to a spherical polishing plate.
CONSTITUTION: The polishing sheet 1 has a connection part in a form of the ring polishing part 1a around its center. The polishing sheet 1 are formed with curved radial grooves 5. The polishing sheet 1 is bonded and secured onto the spherical surface of the polishing plate 3. Due to the grooves 2, cutting scraps can be removed when a lens is lapped, the cutting power can be increased, and the precision of the spherical surface can be improved since the polishing sheet 1 is easily adhered to the polishing plate 3.
