K. Unno et al., HIGH-PRECISION GRINDING AND TURNING FOR OPTICS WITH 3-D PROFILE, International journal of the Japan Society for Precision Engineering, 29(4), 1995, pp. 291-294
Aspherical optics are rapidly being employed in electrical appliances
and office automation equipment, and 3-D profiles are being produced t
o meet these trends. This review paper reports on a newly developed pr
ocessing machine and examples of 3-D profile grinding.
