Title:
OPTICAL INSPECTION DEVICE, LENS, AND OPTICAL INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/154945
Kind Code:
A1
Abstract:
An optical inspection device (100) is provided with an LED (101), a chart (102), a collimator (103), and a mirror (111). The LED (101) radiates light to the chart (102) and thereby radiates the light as light rays which are on-axis with respect to the collimator (103). A pattern of the chart (102) is thereby projected to a center part of an image sensor (130) via the collimator (103) and a subject optical system (120). The mirror (111) reflects light radiated to the mirror (111) via the collimator (103) from among the on-axis light rays. The mirror (111) thereby projects the pattern of the chart (102) to a peripheral part of the image sensor (130) via the subject optical system (120).
