ANNEALING & SLUMPING OPTICAL BLANKS
Advanced Glass Industries has 16 computer controlled annealing ovens, and the ability to anneal optical glass blanks with low residual stress and controlled refractive index. We offer optical glass with refractive index controlled to +/- 0.0001, and extra precision grades with < 4 nm/cm birefringence. We have two massive annealing ovens with a maximum capacity of 90” x 90” x 36” for annealing and slumping very large pieces of optical material. We can also slump or recast optical glass materials up to 30” in diameter and 4” in thickness, in many configurations including optical glass lenses, discs, squares, rectangles, prisms, and more.
