Sapphire : Extreme Surface Hardness and Chemical Resistance.


Sapphire is an extremely tough infrared transmitting material. Excellent mechanical and thermal characteristics make it a superior window material.


U-Optics is recognized in the fabrication of high precision optical windows for demanding applications such as military surveillance & reconnaissance, laser fusion research, FLIR sensing systems, and space applications. Focusing on stringently-controlled fabrication processes that minimize surface damage, U-Optics provides high flexural strength, high reliability sapphire windows. U-Optics can also control wedge, and its orientation on sapphire windows. Our quality assurance program will ensure that each optic and component performs to customer applications.


U-optics offer it’s customers high performance infrared products tailor made to the application needs. Please contact usto discuss your specific requirements.
