Abstract: PURPOSE: To automatically put the microscope in focus on a sample by putting a transparent plane plate on and off the optical path of an optical system and detecting a focusing point as a point between the maximum and minimum of the contrast difference of a microscope image, detected by an image sensor during the period from the insertion to the extraction of the transparent plane plate, from the contrast difference. CONSTITUTION: A contrast detecting means which detects the contrast of an image detected by an image sensor 11 is provided. The transparent plane plate 15 which is put on the optical path 12 of the optical system and put off the optical path 12 is provided. A focus position detecting means places the transparent plane plate 15 in an insertion and an extraction state while moving a sample stage 18 and calculates the difference between outputs of the contrast detecting means which are detected by the image sensor in both the states. A specific focus position is detected from the curve of the output difference which varies during the movement of the sample stage 18. Consequently, the focusing is automatically performed to eliminate the need to move the sample stage, thereby making the operation easy[JPS5088091A]
