<P>PROBLEM TO BE SOLVED: To provide an opthalmologic apparatus that can perform focusing easily even though the wavelength of an illumination light source is changed. <P>SOLUTION: The opthalmologic apparatus is provided with a visible LED 18a and an infrared LED 18b as the light source of index light for indicating the state of a focus. The wavelength of the index light, which is projected on an eye 22 to be examined, is changed by selecting the light emission of the visible LED 18a and the infrared LED 18b, and the position of a split unit 18 on an optical axis is moved based on the selection. <P>COPYRIGHT: (C)2010,JPO&INPIT |
