Optical inspection device having a mirror for reflecting light rays, a method of producing a lens using the optical inspection device, and an optical inspection method using the optical inspection device
An optical inspection device includes: an LED; a chart; a collimator; and a mirror. The LED irradiates the chart with light to deliver light rays to the collimator as on-axis light rays. This allows a pattern on the chart to be projected onto a center of an image sensor through the collimator and an optical system under inspection. The mirror reflects light rays delivered to the mirror through the collimator among the on-axis light rays. This allows the pattern on the chart to be projected onto a periphery of the image sensor through the optical system under inspection.
