PROBLEM TO BE SOLVED: To provide a device for objective measurement of refractive wavefront aberration in a smaller size at lower costs.SOLUTION: A device for objective measurement of refractive wavefront aberration comprises: an illumination optical system that has a light source 101 and irradiates the fundus of a subject eye 150 with illumination light a wavefront measurement system having a Hartmann plate 122 that divides reflective luminous flux reflected from the fundus of a subject eye 150 into a plurality of luminous flux, and a first light receiving part 122 for receiving luminous flux divided by the Hartmann plate 121 an anterior eye illumination system for illuminating an anterior eye part of the subject eye 150 an anterior eye observation system having a second light receiving part 114 for receiving light reflected from the anterior eye part of the subject eye 150 that is illuminated by the anterior eye illumination system and an image data output part 115 for outputting image data of an anterior eye image obtained by the anterior eye observation system. When the light source 101 is set in a range from -3D to -13D, a position of the fungus of the subject eye 150 is set to be substantially conjugate with the light source and a position of the exit pupil is set to be away from an image surface position.COPYRIGHT: (C)2014,JPO&INPIT【課題】小型化・低コスト化を図ることができる他覚的屈折波面収差測定装置を提供する。【解決手段】光源101を備え、被検眼150の眼底に照明光を照射する照明光学系と、被検眼150の眼底から反射された反射光束を複数の光束に分割するハルトマン板121およびハルトマン板121で分割された分割光束を受光する第1の受光部122を有する波面測定系と、被検眼150の前眼部を照明する前眼部照明系と、前眼部照明系で照明された被検眼150の前眼部から反射された光を受光する第2の受光部114を有する前眼部観察系と、前眼部観察系で得られた前眼部像の画像データを出力する画像データ出力部115とを有し、光源101を-3Dから-13Dの間としたときに被検眼150の眼底位置が光源と略共役になるように配置し、射出瞳位置を、像面位置の遠方に配置する。【選択図】図1
