  • Fused Quartz / Fused Silica
    Fused quartz is typically produced by melting crystalline sand and then purifying. Several purity grades of this amorphous material are commercially available. Fused silica is produced after a reaction from SiCL4 gas. Chemical purity is controllable to higher levels than typical when starting
  • The advantages of pure fused silica capillary tubing in medical applications
    Selection of the most appropriate tubing substrate is a fundamental medical device design concern. Key attributes to consider often include items such as material composition and characteristics, surface inertness, biocompatibility, dimensional repeatability, flexibility and cost contribution per
  • Quartz Viewport Transmission Curve
    All MDC quartz viewports are constructed from UV grade fused silica. Sleeve and flange materials are manufactured from high purity 304 stainless steel and vacuum tube grade braze alloys are designed and rated for high and ultrahigh vacuum applications. Fused silica is a polycrystalline, isotropic
  • Commonly Used Wave-transmitting Ceramic Materials for Microwave Heating: Oxide Ceramic System
    The commonly used oxides of wave-transmitting materials for microwave heating mainly include fused silica, glass-ceramic, alumina-based ceramics, etc. Among them, fused silica has stable chemical properties, high thermal shock resistance and excellent dielectric properties due to its atomic
  • Double Surface Super-Polishing Technique
    Hangzhou Shalom EO has successfully developed a double surface polishing method for processing high precision optical windows or substrates, made from N-BK7 and UV Fused Silica, which are one of the most crucial components for Femto-line laser systems.
  • OEM Reticle Products
    patterns. Their substrates are mainly BK7, Soda lime glass and fused silica.
  • Solar Resistant Optical Fiber and Method
    Solar resistant fused silica optical fiber is made by heating the starter rod, drawing the fiber, and preferably immediately diffusing hydrogen into the fiber, then promptly covering the hydrogen diffused fiber with hermetic coating to trap the hydrogen within the fiber. The presence of hydrogen
  • Optical Substrate Material Selection Guide
    The selection of optical substrate material is a vital step to determine the best appropriate optics for your individual applications. The characteristics(optical transmission, refractive index, hardness, etc.) of representative optical materials such as N-BK7, UV Fused Silica, Zerodur Glass
