<p>To provide a lens shape measurement device, comprising: a rotation unit 6 that rotates a lens supported by a stage 12; a laser displacement meter 20; a first moving unit 3 that moves the laser displacement meter 20 in a X-direction; a second moving unit 4 that moves the lens 2 in a Y-direction; and a drive controller that controls a drive of the rotation unit, the first moving unit 3, and the second moving unit 4 in a mirror reflection state in which an incidence angle of the laser beams incident on a measurement target from the laser displacement meter 20, and a reflection angle of the laser beams reflected by the measurement target are equal to each other with a normal line of the lens passing through the measurement target set as a reference, for each of a plurality of measurement targets set on an edge of the lens 2 in a rotating direction of the lens 2.</p> |
