PURPOSE:To easily observe an axis shift by slanting an image pickup surface at an image pickup angle to the optical axis of a microscope according to all focus positions of a real image and a virtual image which are picked up on the image pickup surface. CONSTITUTION:The image pickup surface 2 is slanted at the image pickup angle theta1 to the optical axis 3 of the microscope 1 according to all the focus position of the real image (a) and virtual image (b) picked upon on the image pickup surface 2. Therefore, optical fibers alpha0 and beta0 arranged on an operation surface L slanting at an optical axis angle theta1 to the optical axis 3 form images on alpha and beta on an image pickup surface P through an objective 4. Then the image pickup surface 2 of an image pickup device is arranged matching the position of the image pickup surface P (focus positions of all optical fibers to be picked up). Consequently, images can be picked up so that all the arrayed optical fibers alpha0 and beta0 are in focus at the same time, and the lens barrel of the microscope 1 is shortened to reduce the size of an observation position. |
