Abstract

PURPOSE: To provide stable desired filter characteristics by thermally expanding the filter base material deposited with two or more kinds of transparent dielectrics on either of inner or outer wall of a tubular base while making the pressure in the pipe positive thereby adjusting the deposited film thickness of the transparent dielectric to a desired value.
CONSTITUTION: SiO2-GeO2 base glass and SiO2-B2O3 base glass are alternately chemically evaporated on the inside wall of a tubular base 21 composed of quartz glass tube to form a multilayer film interference filter base material 20 having a transparent dielectric deposited layer 22 as A process. Next, as B process, the inside diameter of this multilayer film interference filter base material 20 is heated and gradually expanded while the pressure therein is being made positive, whereby the thickness of the transparent dielectric layer 22 is reduced down to a required value. As the final C process, a plate-form multilayer film interference filter 10 is cut out from the tubular multiplayer interference film base material 20, whereby the multilayer interference filter 10 having required filter characteristics is produced.
