POLISHING METHOD OF OPTICAL CYLINDRICAL SURFACE, POLISHING DEVICE USED FOR THIS POLISHING METHOD AND POLISHING TOOL POLISHING DEVICE USED FOR THIS POLISHING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a polishing device of an optical cylindrical surface, which precisely finishes a shape in the bus bar direction of a cylindrical lens, in the light of the relationship between the ratio of the length in the bus bar direction to the length in the bus bar direction of the cylindrical lens and a change in polishing amplitude in the bus bar direction.;SOLUTION: The polishing device 3 polishes the cylindrical surface 2 of the cylindrical lens 1, by using a polishing tool 6 having the ratio of the length in the bus bar direction to the length in the bus bar direction of the cylindrical lens 1, which exists in a range of changing a shape of a bus bar of the cylindrical lens 1 over a range from a concave to a convex by a change in the polishing amplitude in the bus bar direction.;COPYRIGHT: (C)2008,JPO&INPIT
