Abstract:
We propose a method for extending the antireflection zone of highly curved spherical optical components via applying a combined layered coating synthesized in a vacuum chamber with use of a circular diaphragm. The motion path of an arbitrary point on the spherical optical component involved in a dual rotation is numerically simulated and the antireflection zone formed by a combined single-layer coating on the optical component surface is determined.

Keywords:
antireflection coating, highly curved optics, antireflection zone.
