MEASUREMENT OF FORM OF SPHERICAL AND NEAR-SPHERICAL OPTICAL SURFACES

Rotational motions between a displacement-measuring probe and an optical test surface define a spherical or near spherical datum surface against which measurements of the probe are taken. The probe has a measurement axis that is maintained substantially normal to the optical test surface during the...
