PROBLEM TO BE SOLVED: To obtain a clear image which is in focus with both observation surfaces, when simultaneously imaging the two observation surfaces whose positions are different in a depth direction.SOLUTION: An imaging device 1 comprises light-receiving surfaces 51a and 52a for receiving two observation lights with different wavelength which are generated from two observation surfaces B and C whose positions are different in a depth direction of a specimen A imaging portions 51 and 52 for obtaining images of the two observation surfaces B and C and optical path length adjusting means 6 and 52 for adjusting the optical path length from the observation surface C of at lease one observation light to the light-receiving surface 52a, according to a distance z in the depth direction between the two observation surfaces B and C.COPYRIGHT: (C)2012,JPO&INPIT【課題】深さ方向に位置が異なる2つの観察面を同時に撮像する場合に、いずれの観察面にも焦点の合った鮮明な画像を取得する。【解決手段】試料Aの深さ方向に異なる2つの観察面B,Cから発生した互いに波長の異なる2つの観察光を区別して受光する受光面51a,52aを有し、2つの観察面B,Cの画像を取得する撮像部51,52と、2つの観察面B,C間の深さ方向の距離zに応じて、少なくとも一方の観察光の観察面Cから受光面52aまでの光路長を調節する光路長調節手段6,52とを備える撮像装置1を提供する。【選択図】図1
