- Hemex Sapphire− is world renowned for showing no stress birefringence, no bubbles and no other defects. This grade of material is used to produce optics of 1/20th wave and better.
- HEM (LAOS)− Low Absorption Optical Sapphire – used in applications where minimal photon absorption is critical to performance.
- HEM (LAOS 193)− Vacuum Ultra Violet Sapphire – a special sapphire product optimized for semiconductor applications at and near 193nm.
Our Advanced Materials Group produces the world’s highest quality sapphire called Hemex Sapphire. This special sapphire has perfect crystalline structure with no detectable light scatter and is capable of supporting finished optics with transmitted wave front values of 1/20 wave peak to valley and better. Hemex material has been independently characterized using Berg-Barrett X-Ray topography, which concluded that no dislocations in the crystalline structure could be found. These superior crystals are utilized in applications where there can be no compromises making Hemex the absolute pinnacle of sapphire quality.
Hemex is used in critical engineering applications where zero defect sapphire is needed to support the fabrication of sophisticated optical components and systems. These applications can include high power laser optics, acoustic wave devices, 1/20 wave optics and neutron filters.
