摘要:
Refractive projection objective with a numerical aperture greater than 0.7, consisting of a first convexity, a second convexity, and a waist arranged between the two convexities. The first convexity has a maximum diameter denoted by D1, and the second convexity has a maximum diameter denoted by D2, and 0.8
