Method for producing an image dissector
First Claim
1. A method of producing an image dissector comprising the steps of:
- (a) providing a single rectangular cross-section glass rod having a core of optical fiber with a thin layer of acid-soluble glass adjacent only one side surface or only two opposite surfaces thereof, and thermally forming the thus-coated glass rod using a heating element;
(b) arranging a plurality of the formed glass rods of step (a) in a matrix configuration to form an optical conduit by placing the acid-soluble glass coated side surface of each of said individual coated rods in parallel planes with respect to each other;
(c) thermally forming the matrix configuration of rods of step (b) using a heating element thereby fusing the rectangular rods together into a unitary body;
(d) shielding one end of the fused body of step (c) with an acid resistant material, then dissolving and removing the thin layers of said soluble glass by subjecting the fused, shielded body to an acid solution, and separating the acid-treated portion of the conduit into a plurality of ribbon-shaped layers having the adjacent uncoated glass rod surfaces fused to each other; and
(e) selectively arranging the ends of the layers of step (d) in a straight line which corresponds to the arrangement in the matrix end of the body and binding the thus arranged layers to each other forming an image dissector having one end in a straight line configuration and the other end thereof in a matrix configuration.

Abstract
A method for producing an image dissector having one end portion fixed in a matrix type and the other end portion fixed in a straight line. A conduit is formed by arranging plurality of single rods having an acid-soluble glass layer on one of side surfaces of every single rod so that said acid-soluble glass layers will be arrayed in parallel planes and by subjecting said single rods to thermal forming. Said conduit is soaked in acid, after shielding its one end portion, in order to dissolve said acid-soluble glass layers and to separate the other portion into ribbon-shaped layers. An image dissector is produced by arraying end portions of separated ribbon-shaped layers in a straight line and fixing them together.
