A method for producing a fused silica glass containing titania includes synthesizing particles of silica and titania by delivering a mixture of a silica precursor and a titania precursor to a burner, growing a porous preform by successively depositing the particles on a deposition surface while rotating and translating the deposition surface relative to the burner, and consolidating the porous preform into a dense glass.

Disclosed are process and apparatus for inspecting internal inclusions in internally transmissive substrates. The process involves applying a black coating to one major surface of the substrate, submerging the substrate in a refractive index-matching fluid, and scanning the substrate with a collimated light beam. The scattered light signals produced by the inclusions can be detected by the human eye or by using a light detector. By the use of index-matching fluid and the black coating, the signal-to-noise ratio of the process and apparatus are enhanced. A preferred black coating is one cured from an electron beam or photo polymerizable coating composition applied to the major surface. The process and apparatus are particularly suitable for inspecting internal inclusions in an internally transmissive substrate having considerable amount of surface defects or contoured surface that prevent it from inspection in a gas medium.

A method of making glass tubing includes assembling together a first glass rod having at least one bore and a second glass rod having at least one bore to form a single glass unit, shaping an outer surface of the glass unit to a desired cross-section, and drawing the glass unit to form a glass tubing having a predetermined outer and inner dimension.

A method for forming a fused silica glass includes delivering a silica precursor to a burner and passing the silica precursor through the flame of the burner to form silica particles, depositing the silica particles on a planar surface to form a flat, porous preform, dehydrating the porous preform, and consolidating the porous preform into a flat, dense glass.

Method for producing fused silica and doped fused silica glass

A method of producing a glass-plastic, laminated, ophthalmic lens structure in a continuous operation. A thin, flexible, plastic adhesive layer is applied to a glass element to form a composite body that is inserted in a cylindrical gasket in such manner as to fit snugly and be sealed from the ambient. A monomeric formulation is flowed onto the adhesive layer and cured to form a laminated lens blank.
