Since 1974 Glass Fab Inc. has met customers stringent specifications by providing fabricated parts made of optical glass, filter glass, fused quartz and silica, low expansion materials, and various other optical materials. Because of this, Glass Fab has grown to become a world leader in fabricating quality optical blanks.
With over 100,000 lbs of raw inventory, our skilled craftsmen can fabricate most parts rapidly and consistently. Most materials are melt lot controlled so we can provide traceable optical data with orders. With our test equipment (where the material quality and color will allow), we can select to specifications beyond the manufacturers standard specs including bubble quality, stress birefringence, striae, and homogeneity.
Our stock consists of, but not limited to, the following:
Materials designed for their index and dispersion properties. Typical use are in lens systems. Our stock includes materials from: CDGM, Corning, Hikari, Hoya, Ohara Pilkington, Schott, Sumita, and others.
Materials designed for their transmission or absorption properties. Extremely varied uses from medical to fire detection systems. Our stock includes materials from: Hoya, Isuzu, Kopp, Optima, Schott, and others.
Materials with low thermal expansion and high transmission. Uses range from substrates to high powered laser systems. Our stock includes materials from: Corning, GE Momentive, Heraeus, Nikon, Ohara, Tosoh, and others.
Materials with low thermal expansion (some extremely low). Typical uses are substrates, test flats, and mirrors. Our stock includes materials from: CDGM, Corning, Ohara, Schott, and others.
Our stock includes some ceramics, float glasses, and others.
With our ovens, we can re-anneal most materials to fine and precision annealed tolerances. We can also reslump most materials into sizes beyond the raw material size (ie. taking 40mm thick strip and making material 50mm thick).
