Title:
METHOD FOR MEASURING SEMIFINISHED BLAND AND PROCESSING METHOD
Document Type and Number:
Japanese Patent JP2011248348
Kind Code:
A
Abstract:

To provide methods for measuring a semifinished blank and for checking a working condition of the same, in the semifinished blank where a coating member is applied to either one of a front surface or a rear surface, capable of calculating a value of a predetermined optic characteristic without removing the coating member and checking whether the working condition is satisfied based on a calculated result.

An amount of prism of a semifinished blank 11 can be calculated based on a measurement of reflecting light at the concave surface side obtained by irradiating a semifinished blank 11 which has a block piece 13 attached to a convex surface side by an alloy 12 with light in a direction from the concave surface side to the convex surface side.
