Physical and Optical Properties of Surfaces Generated by Diamond-turning on an Advanced Machine

Source

A superprecision, two-axis, air-static bearing, diamond-turning machine of advanced design has been previously described at this Conference and is now operational. The microtopography and other physical characteristics of surfaces turned by this machine will be examined in detail. Some effects of machining parameters will be briefly discussed. The ability of this machine to turn surfaces with very small slope errors (< 10-3C) and small rms roughness (∼ 10 Å) is discussed with relation to the resulting optical absorption, scattering, and laser damage resistance. The characteristics of the machine which permit these high quality surfaces are identified, and some projections are given to the future application of diamond-turned optics at near infrared or visible wavelengths.
