Sapphire Rods for medical device, accurate machine and inspection instrument
  • Extremely hard, strong and wear resistant
  • Excellent thermal conductivity/heat resistance
  • Exceptionalchemical stability
  • Excellent transmission bandwidths (UV to IR)
  • Blank substrates, AR-coated pieces, and precision windows are available
  • Sapphire Rods are used in a wide range of applications. A sapphire rod can be made with all surfaces polished for optical and wear applications or with all surfaces fine grind (un-polished) to serve as an insulator. Sapphire Rods are available in a range of outer diameter and lengths. OD’s as small as .0175″.

    Typical Applications: Pumps, Light Pipes, Spacers, Insulators, Wear Applications

    Sapphire possesses nice light transmission in 0.20 ~ 5.50μm wave band, is ideal for laser and infrared optical materials. Products widely used in endoscope,watch glass, optical lens, surface acoustic wave filter, military infrared window, optical filter, observation window for high/low temperature and cosmetic instrument windows, etc. We can provide anti-reflection film, high-reflective film, dielectric film, filter film and metallized film services.

    Sapphire Rods and ceramic rods according to the type of material. According to the type of part structure, they are divided into flat rods, single convex rods, double convex rods, rotor horizontal pins, special-shaped rods, blind hole rods, etc.

    Sapphire Rods are mainly made of synthetic sapphire single crystals with corrosion resistance, wear resistance, thermal and chemical stability, and good optical properties. After being made into high- precision components such as stopper rods and measuring rods, it often used in injection plug rods, measuring rods, laser rods, laser rangefinders, laser guidance meters, gyroscopes applications and are widely used in environments such as corrosion resistance, wear resistance, and high thermal conductivity.

    Sapphire Rods are superior for rod bearing and standoff applications that involve high abrasion and wear while maintaining dimensional stability.

    Sapphire Rods are ideal for rollers and standoffs in high temperature furnace systems. Sapphire Rods remain straight and dimensionally "perfect" up to 1800C. Because of sapphire's extreme chemical resistance, many materials will not stick to sapphire in spite of high temperatures.

    Sapphire Rods and tubes are so chemically and bio-inert, they are the perfect materials for medical, pharmaceutical, semiconductor and other applications where maintaining purity and health is critical.

  • Anti-reflection coatings are also available at your specified wavelength.
  • Sapphire transmits ultraviolet light, but sometimes exhibit fluorescence when subjected to powerful ultraviolet sources. For this reason, they are best suited for use with visible to infrared wavelengths.
  • Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
  • sapphire rods are the go to material in so many applications. "Exceptional" applies to sapphire's performance under numerous conditions: mechanical, optical, thermal and chemical. In these cases, a sapphire rod is without a peer.
