Sapphire is the best medium for lenses and other optical applications that require a broad spectrum of light transmission and high optical clarity. Sapphire lenses, reflectors and optics have the ability to transmit a wider range of infrared than any other standard glass optics. For UV light transmission, sapphire is the best material next to UV-grade quartz.
We grind and polish a variety of optical sapphire lenses for Lasers, Endoscopes, LEDs & many other applications. Our in-house engineering department is here to insure your requirements are fulfilled.
