Abstract
In one example, a method for making diagonal openings in photodefinable glass includes exposing part of a body of photodefinable glass to a beam of light oriented diagonally to a surface of the body at an angle of 5° or greater measured with respect to a normal to the surface of the body and removing some or all of the part of the body exposed to the light beam to form a diagonal opening in the body.
Claims10
A method, comprising:
- concurrently forming a plurality of spaced nonparallel bundles of nonparallel rays;
- exposing part of a body of photodefinable glass to the plurality of nonparallel bundles of nonparallel rays, each bundle oriented diagonally to a surface of the body at an angle of 5° or greater measured with respect to a plane normal to the surface of the body;
- and
- removing some or all of the part of the body exposed to the plurality of nonparallel bundles of nonparallel rays to form a diagonal opening in the body.

A method, comprising:
- concurrently forming a plurality of spaced nonparallel bundles of nonparallel rays;
- exposing part of a body of photodefinable glass plate to the plurality of nonparallel bundles of nonparallel rays, each of the plurality of nonparallel bundles of nonparallel rays being oriented diagonally to a surface of the plate at a different angle within the range of 5-50° measured with respect to a plane normal to the surface of the plate, and
- removing some or all of each part of the glass plate exposed to the plurality of nonparallel bundles of nonparallel rays to form multiple openings through the glass plate, each of the multiple openings being oriented diagonally to the surface of the plate at a different angle.
