Title: Shape-measuring instrument
Inventor: TAZAKI KENJI
IPC: G01B9/02
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a shape-measuring instrument, capable of setting a specified space between a reference surface and a tested surface without damaging them, even if the space is hard to check visually when the reference surface and the tested surface are to be set at the space. SOLUTION: Measure light 17 is emitted between the reference surface 7a and the tested surface 8a from the direction, crossing the optical axis 14 of the surface 7a, and the light 17, having passed between the two surface 7a, 8a, is received by a light receiving device 16. The amount of light received by the receiver 16 is reduced by the amount of light which the surface 8a intercepts the light 17. When the surface 8a is to be disposed keeping a prescribed space from the surface 7a, in order to measure the shape of the surface 8a, the amount of light 17 received by the receiving device 16 is monitored. When the amount of received light becomes equal to or less than a prescribed value, a motor or the like for driving a tested lens 8 is stopped, so that the surface 8a does not come any closer to the surface 7a.  This causes the surfaces 7a, 8a to be set at the proscribed space in a noncontacting manner.
