近年来,精密加工技术正在取得惊人的进展。超微细加工的尖端技术—半导体存储器领域,已在建立加工最小线宽为0.5μm的16MD-RAM的光刻(蚀)技术。同时,在光电子学领域中,随注射机及其复映技术的发展,包括非球面透镜的各种透镜,一般都采用模具的连续成形法制造。由于该成形法的建立,以往价格很高的非球面透镜,以光盘摄像透镜为首,在电视摄像
In recent years, precision machining technology is making amazing progress. Ultra-fine processing of cutting-edge technology - semiconductor memory, has been established to process the minimum line width of 0.5M 16MD-RAM lithography (etching) technology. In the meantime, in the field of optoelectronics, with the development of the injection molding machine and its rehearsal technology, various lenses including aspherical lenses are generally manufactured by continuous molding of a mold. Due to the establishment of the forming method, aspheric lenses, which have been expensive in the past, are mainly made up of an optical disc imaging lens and are used in television imaging
