Patent ID: 8705024

Claim:
A wavefront aberration measuring device, comprising: a first table means being movable on a plane surface; a point light source forming means for forming a point light source, being mounted on said first table means; a second table means for mounting a measuring object thereon, being able to rotate; a Shack-Hartmann sensor for detecting a light emitting from the point light source, which is formed by said point light source forming means, and transmitting through a lens to be inspected, which is mounted on said second table means; and a signal processing means for processing an output signal from said Shack-Hartmann sensor detecting the light, and thereby obtaining wavefront aberration of said lens to be inspected, and further comprising an adjustment means, wherein said adjustment means adjusts an inclination and a position of said Shack-Hartmann sensor or an optical path of the light transmitting through said lens to be inspected, so that the light emitting from the point light source of said point light source forming means and transmitting through the lens to be inspected, which is mounted on said second table means, is detected by said Shack-Hartmann sensor upon a pupil surface of said lens to be inspected or a surface conjugate with said pupil surface, depending on a position of said point light source.
