    Abstract: A laminated or single layer glass cylinder and its method of making are disclosed. The laminated cylinder glass is a precursor component to enable making subsequent drawn tubing having high optical quality. The laminated cylinder glass may comprise a first layer of glass as a clad glass and a second layer of glass as a core glass. The second layer of glass may be bound to the first layer of glass. The second layer may have a higher CTE from about 5×10−7/° C. to about 100×10−7/° C. than the first layer of glass. The first layer and second layer of glass may have different softening points within about 200° C. of each other. In some embodiments, the first layer and second layer of glass may have different softening points from about 50° C. to about 200° C. of each other.

    Abstract: Provided herein are measurement systems including a micrometer assembly for receiving a length of tubing, the micrometer assembly including a plurality of non-contact optical micrometers disposed around the length of tubing for measuring an outer diameter (OD) at a first plurality of positions along a circumference of the length of tubing. The measurement system may further include a displacement gauge assembly for receiving the length of tubing from the optical micrometer assembly, the displacement gauge assembly including a plurality of non-contact gauges disposed around the length of tubing for measuring a wall thickness at a second plurality of positions along the circumference of the length of tubing. A controller receives the OD measurements and thickness measurements, and determines an inner diameter and a concentricity of the length of glass tubing based on an index of refraction of the length of glass tubing, the OD measurements, and the thickness measurements.

    Abstract: An apparatus and methods for bending sheet glass are disclosed. The present invention improves on the state-of-the-art by providing apparatus and methods that prevent unwanted distortion of the glass sheet. The apparatus and methods utilize localized heating at the bend to allow for overall glass sheet temperatures to be reduced, along with optional mechanical devices for improved bend quality.
