surfaces with generated curves



Advanced Glass Industries can generate spherical, parabolic, and aspheric curves in a wide variety of optical materials from the softest optical glasses, to more demanding materials such as fused quartz and fused silica. Recent additions to our facility include aCooke generator for parts up to 24" in diameter, a second Rogers and Clarke G-300 generator, as well as a G-150 generator for smaller parts. Our CNC machining centers offer options for generating spherical curves on larger parts, such as telescope mirror blanks. We can generate aspheric optical glass blanks up to 27.000” in diameter and 4.500” thick, with tolerances to 0.015”, and centration to within 0.010”.
