<P>PROBLEM TO BE SOLVED: To provide a correcting device for an ophthalmologic apparatus which enables a highly reproducible correction during the measurement of flare and of cells and enables precise flare measurement and/or cell measurement. <P>SOLUTION: The correcting device 10 comprising a neutral density filter 2 for adjusting intensity of laser beams and a reflector 1 disposed in the neighborhood of a position of a light focus point of the laser beams is provided to correct the ophthalmologic apparatus which scans an anterior chamber of an eye to be examined with the laser beams, receives scattered light from inside of the anterior chamber by the laser beams at a light receiving means, and analyzes light receiving signals to perform prescribed ophthalmologic measurement. The reflector 1 is disposed to prevent the light receiving means from receiving surface reflection or reverse side reflection by the laser beams, and the correcting device corrects by measuring the scattered light from the reflector when the reflector is irradiated with the laser beams. Since the scattered light which is the same as a protein or the particles of latex is reliably measured, this structure achieves the highly reproducible correction. <P>COPYRIGHT: (C)2007,JPO&INPIT |
