ABSTRACT:
Measurement data (measured results) obtained under a plurality of conditions and image data and/or numerical data corresponding to the measured results are displayed collectively or selectively. An optical characteristics measuring device (100) measures/displays, for example, the optical characteristics of an eye to be measured (60) as an object. A first lighting optical system (10) includes a first light source (11) for applying an optical flux of a specified pattern to the eye to be measured (60). A first light receiving optical system (20) includes a first light receiving unit (23) for receiving light reflected from the eye (60). A light transmitting/receiving optical system (30) mainly conducts an alignment adjustment, and includes a second light receiving unit (35) for receiving light reflected from the eye (60). A common optical system (40) is disposed on the optical axis of a light flux emitted from the first lighting optical system (10), and is commonly included in the first lighting.
