This paper discusses the possibilities of obtaining fast sinterform focusin
g systems based on a wavy correction surface. Single-component sinterform o
bjectives with diameter 14 mm, thickness 3 mm, and aperture angle 0.26, pos
sessing small spherochromatic aberrations in the visible and near-IR region
s, have been developed, fabricated, and tested. (C) 2000 The Optical Societ
