To provide a measurement optical device that can accurately measure optical characteristics.SOLUTION: A measurement optical device comprises: a first optical member 11a that receives incidence of image light GL from a virtual image display device VD to be measured and emits the incident image light GL; a second optical member 11b that receives incidence of the image light GL emitted from the first optical member 11a and provides telecentricity to the incident image light GL before emitting the light; a light receiving member 12 that is arranged along a first direction in which the first optical member 11a and the second optical member 11b are located side by side and receives the image light GL emitted from the second optical member 11b; and an adjustment member that adjusts a light path to form the image light GL received on a light receiving surface 12r of the light receiving member 12 into an image.SELECTED DRAWING: Figure 4 【課題】光学特性を精度よく測定できる測定光学装置を提供すること。【解決手段】測定対象である虚像表示装置ＶＤからの画像光ＧＬが入射し、入射した画像光ＧＬを出射する第１光学部材１１ａと、第１光学部材１１ａから出射された画像光ＧＬが入射し、入射した画像光ＧＬをテレセントリック性を有するように出射する第２光学部材１１ｂと、第１光学部材１１ａと第２光学部材１１ｂとが並ぶ第１方向に沿って配置され、第２光学部材１１ｂから出射された画像光ＧＬを受光する受光部材１２と、受光部材１２の受光面１２ｒにおいて受光する画像光ＧＬを結像させるように光路を調整する調整部材と、を備える。【選択図】図４
