Fused silica or fused quartz has good thermal stability. Fused silica lenses or fused quartz lenses have excellent properties and chemical purity. They have excellent transmission and adapt to high operating temperatures. These fused silica lenses are the first choice in many areas of laser and imaging applications, especially those used in UV wavelength regions.
fused silica lenses mainly include spherical lenses, aspheric lenses, cylindrical lenses, and ball or half-ball, hemispherical lenses.
He Rui Optics can produce various of high-quality fused silica lenses made from UV grade fused silica glass and IR grade fused silica glass. Commonly available materials are Chinese JGS1, JGS2, JGS3, Corning 7980, 7979,8655 ,SK1300, SK1310 and so on.
