SENSORS AND DETECTORS

Sapphire UV and IR transmission properties in combination with ability to withstand harsh chemicals, high pressures and temperatures offer strong advantages for Fire and IR Detectors, protective windows and thermocouple protection sheaths for remote sensors and optics for harsh environments such oil well drilling, chemical processing and other industrial processes.

DETECTOR WINDOWS

Polished windows or ground blanks available up to 300 mm diameters. Various shapes and sizes available.

OPTICAL RODS AND LIGHT PIPES

Ground or polished rods up to 300mm lengths and up to 50 mm diameters.

SEMICONDUCTOR PROCESS EQUIPMENT

Sapphire’s durability and resistance to fluorine chemistries and high temperature process environments up to 2,000°C offer advantages over other materials such as quartz, alumina and other ceramics. Sapphire often replaces these materials in process chamber environments. Key products include:

CHAMBER, HEATER, AND MICROWAVE WINDOWS

Available in many shapes and size in dimensions up to 250mm x 325mm and diameters up to 300mm.

WAFER LIFT PINS

Sapphire rod shaped and ground to customers specifications.

PLASMA TUBES

Tubes up to ~2” OD and 12+” lengths finished to tight tolerances.

FOCUS RINGS AND CHAMBER LINERS

Available in diameters up to 300mm and thickness up to 100mm.

DUMMY WAFERS AND WAFER CARRIERS

2”, 4”, 6” and 8” wafers available with ground or polished surfaces and custom thicknesses.

INSTRUMENTATION AND ANALYTICAL PROCESSING

Sapphire's chemical resistance, and ability to withstand high temperature and high pressure, and ability to transmit in UV and IR ranges make it ideal for applications such as mass spectrometry, spectrophotometry, digestive cells, and other analytical applications. Sapphire often replaces quartz and glass to improve equipment and consumables lifetimes. Key products include:

WINDOWS AND WINDOW BLANKS

Round, square, rectangular windows available in customer thicknesses and sizes in both UV and IR grades.

THERMOWELLS AND THERMOCOUPLE PROTECTION SHEATHS

Small and large sapphire tubes with one or both ends capped or plugged. Dimensions up to 1” OD and 12” lengths available.

MEDICAL AND LASER

Sapphire's optical transmission range, durability, ability to be shaped into sharp edged products and inertness with human tissue offer advantages for specific medical laser applications for dermatology, ophthalmology and dentistry. Sapphire products are also used for surgical tools, implants, braces and in a variety of windows for medical equipment such as endoscopes and laser windows. A variety of polished windows, shaped parts and blanks available.

DEFENSE AND AEROSPACE

Sapphire is used due to its broad transmission range in the UV through IR spectrum, resistance to scratching and corrosion in sand or salt environments and its impact resistance. Key Defense and Aerospace applications include Targeting Systems and Protected Optics for fighter jets, UAVs and Helicopters, FLIRs and Enhanced Vision Systems for aircraft, Sensor Suites and Shaped Optics for land, air and sea vehicles, Missile Domes, Countermeasure Lamps and Transparent Armor Systems. Key products include:

POLISHED WINDOWS AND WINDOW BLANKS

For targeting systems, FLIRs, UAVs, sensor suites, optics and armored windows. Circular windows with dimensions of up to 12" diameter, 10" x 14" rectangles with thicknesses up to 2" or greater.

TUBES AND OPTICAL RODS

Diameters up to ~2" and lengths up to 12+" for counter measure lamps and optical light pipes and sensors.

Our LANCE project is setting a new standard in very large area, high quality sapphire.

Sapphire is ideal for high-performance optical applications due to its physical properties. Sapphire offers optical transparency, physical strength, resistance to abrasion and corrosion, temperature durability, chemical inertness, and bio-compatibility. Rubicon’s capability to produce multiple shapes and products such as very large size sapphire windows and blanks of excellent optical quality and strength help expand the range of applications available to our customers to utilize high-performance sapphire parts.
