ABSORPTION TYPE MULTILAYER FILM ND FILTER CHIP AND METHOD OF MANUFACTURING SAME, METHOD OF JOINING SAME, DIAPHRAGM BLADE WITH SAME, AND METHOD OF MANUFACTURING DIAPHRAGM BLADE

摘要

PROBLEM TO BE SOLVED: To provide methods of manufacturing an absorption type multilayer film ND filter chip and a diaphragm blade with absorption type multilayer film ND filter superior in productivity, and to provide a method of joining the absorption type multilayer film ND filter chip. SOLUTION: In the method of manufacturing the absorption type multilayer film ND filter chip by press cutting an absorption type multilayer film ND filter sheet provided with an absorption type multilayer film made by alternately laminating an oxide dielectric film and a metal film on at least one side of a resin film substrate. At least one part of the absorption type multilayer film at a portion 6 of a cutting line 5 when press cutting the absorption type multilayer film ND filter sheet or a portion 7 to be a joining region with the diaphragm blade material is removed by a laser scribing method.
