| description | A lens shape measuring apparatus measures a peripheral shape of a lens in order to measure the peripheral shape of the lens accurately according to a non-contact technique. The lens shape measuring apparatus includes: a lens holding mechanism section for holding the lens with the holding axis from the side of a lens surface; and a laser displacement meter for measuring a lens peripheral shape by irradiating a laser beam to the periphery of the lens and receiving a reflected light thereof. The laser displacement meter is installed such that a light projecting section for projecting a laser beam and a light receiving section for receiving a laser beam are aligned in a direction perpendicular to an axis line of the holding axis. The lens shape measuring apparatus causes the lens holding mechanism section to change a lens holding position without changing the axial direction of the holding axis, and causes the laser displacement meter to irradiate a laser beam to the lens periphery at each lens holding position and to measure the peripheral shape of the lens. |
