EQ200
Quartz ingots produced by the flame fusion method can be processed into transparent quartz wafers, square plates, flanges, and other components, which are used in applications such as optical windows and semiconductor‑grade quartz parts.
It can also be re‑hot‑formed to produce quartz blocks or plates of special specifications, and can be drawn into quartz tubes and rods. It is used as a material for semiconductor components and as an auxiliary material in the manufacture of optical fibers.
OH content typically ranges from 120 to 260 ppm.
Our EQ200 series of optical components are made from high‑quality JGS‑2 material, which is transparent across the ultraviolet and visible spectral ranges and exhibits no absorption bands between 220 and 2500 nm. They are widely used as UV–visible observation windows in a variety of industries.
