Abstract:
A detection device includes an illumination optical system configured to illuminate a first alignment mark for detecting a position of an object in a first direction and a second alignment mark for detecting a position of the object in a second direction and a detection optical system configured to detect light beams from the alignment marks. The illumination optical system includes an optical element disposed at a position optically conjugate to a surface to be illuminated, and the optical element includes a region configured to form an illumination light beam for illuminating a first portion of the surface to be illuminated with a first angular distribution and a region configured to form an illumination light beam for illuminating a second portion of the surface to be illuminated with a second angular distribution.

Claim (Index 13):
An illumination optical system configured to illuminate a first alignment mark for detecting a position of an object in a first direction and a second alignment mark for detecting a position of the object in a second direction that is different from the first direction, the illumination optical system comprising: an optical element disposed at a position optically conjugate to a surface to be illuminated, the optical element including a region configured to form an illumination light beam for illuminating a first portion of the surface to be illuminated with a first angular distribution and a region configured to form an illumination light beam for illuminating a second portion that is different from the first portion of the surface to be illuminated with a second angular distribution that is different from the first angular distribution,\n wherein the first alignment mark in the first portion of the surface to be illuminated is illuminated with the first angular distribution, and the second alignment mark in the second portion of the surface to be illuminated is illuminated with the second angular distribution.
