Our Sapphire tubes are used as a superior alternative to quartz, alumina, and silicon carbide in semiconductor processing applications. In addition, our Sapphire tubes are used in various analytical instruments in lamp applications that transmit visible, infrared or ultraviolet light, often with high intensity at high temperatures and pressures. Potentially Sapphire tubes could be used as capillary needles for laser medicine as discussed in this Journal of Biomedical Optics article.

Size Range
Unlike materials grown by methods that require extensive post-growth machining, single-crystal tubes are grown to "near-net" size, minimizing finishing costs.
