Steps Towards 8m Honeycomb Mirrors V: a Method for Polishing Aspheres as Fast as F/1
Published online by Cambridge University Press: 12 April 2016
Abstract
A method is proposed for polishing fast aspherics with a lap whose shape is continuously changed under computer control as it moves over a rigid mirror blank. The required changes of radius, astigmatism and coma in a circular lap are made with edge bending levers and tensioning members with screw actuators. This method of bending has been demonstrated in the laboratory.
