METHOD FOR MEASURING THICKNESS OF ADHESIVE LAYER IN CEMENTED BODY, CEMENTED LENS, AND CEMENTED BODY

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring the thickness of an adhesive layer in a cemented body, which properly measures the thickness of an adhesive layer regardless of the magnitude of a difference in refractive index of elements in a cemented body.;SOLUTION: The method for measuring the thickness of an adhesive layer of a cemented body having a first layer and an adhesive layer having nearly the same refractive index as the first layer and welded to the first layer, has: a reflective layer formation process S10 for forming, on the interface between the first layer and the adhesive layer, a reflective layer having higher reflectivity than the interface; a measuring light application process S20 for applying measuring light onto the reflective layer; a reflected light acquisition process S30 for acquiring the reflected light of the measuring light reflected by the reflective layer; and a reflected light analysis process S40 for calculating the thickness of the adhesive layer on the basis of the obtained reflected light.;COPYRIGHT: (C)2011,JPO&INPIT
