Rayotek specializes in slumping and molding soda lime glass, borosilicate** (Pyrex™), fused quartz, fused silica, and glass ceramic for industries where the quality, purity, mechanical and optical characteristics of glass are critical. We provide glass molding and slumping for a wide range of industries. We excel in precision glass molding and slumping to create both simple and complex curves and shapes with tolerances comparable to precision ground parts. For most high-volume applications, our precision glass molding process is much faster and far more cost effective than traditional grinding processes.Borosilicate molding is used when the thermal, mechanical and chemical conditions are too much for standard glass. The relatively low material cost and ease of borosilicate molding make it an excellent choice in many applications. The low coefficient of expansion makes borosilicate the best choice for thermal environments. It is thermally stable up to 450C for continuous use and 600C for short periods. Additionally, the minimal devitrification occurring during borosilicate molding means high quality surfaces can be maintained.

Rayotek is a premier wafer, shield & precision sapphire optical windows manufacturer. Because of sapphire's durability and scratch resistance, it is far superior to any type of glass for window, wafer, optical and shield applications. In addition, sapphire transmits more into the infrared and ultraviolet range than most glasses. Sapphire is also more temperature and chemical resistant than any other transparent (and most non-transparent) materials.Sapphire shields & blanks Sapphire sheet & flat stock Sapphire semiconductor wafers Sapphire safety & blast shields Sapphire optical windows for camera & imaging protection Sapphire windows for semiconductor plasma & chemical etching applications Scratch & impact resistant sapphire scanner windows, PDA windows & display windows

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 reflectors, lenses and optics. For UV light transmission, sapphire is the best material next to UV-grade quartz. Rayotek grows, grinds and polishes a variety of optical sapphire parts for endoscopes, lasers, LEDs & many other mini and micro optics applications, including: Sapphire optics for endoscopes & other medical optical applications Infrared (IR) sapphire optics for laser systems Sapphire optics for LEDs & all other mini & micro lighting applications Sapphire lenses, reflectors & holders for fiber optics applications Sapphire light pipes & light guides for IR transmission & furnace pyrometry Rayotek is a precision sapphire optics, reflector and lens manufacturer providing sapphire products of superior quality. Our in-house engineering department is here to insure your requirements are fulfilled.

Rayotek designs, develops and manufactures sapphire xenon flash lamps and plasma lamps for a wide range of applications. Due to its unique properties, sapphire is a superior material for high-pressure and high-temperature lamps. Sapphire lamps are far superior to fused quartz because they do not devitrify, do not UV solarize, and are much more durable. The use of sapphire is even more critical when high mechanical or thermal stress is involved.
