ATT  produces a wide range of glass and crystalline materials for optical, laser, lighting, electronics and other applications.  Optical products are engineered to meet the most rigorous quality standards and produced from ultra-high purity materials.  Production of crystalline materials is overseen by expert, ATT ' s crystal growth production emphasizes ultra high purity elemental and compound materials produced in the form of single crystals, polycrystalline pieces, boules, and crackle, powders, ingots, discs, shaped charges and rods. We are recognized specialists in custom-grown single and polycrystalline materials of any of the III-V and II-VI compounds when special orientations, purities or dopants are required. Unlike many other producers, our facilities are also set up to cost-effectively produce small or pilot scale lots. All production materials are analyzed and certified prior to shipping.
