Abstract
In order to enable an easy acquisition of a bright excellent differential image and an excellent ordinary image of an object requiring observation, the photoelectric microscope using a position sensitive device in accordance with the present invention comprises: a laser light source; an objective lens for collecting, onto the object requiring observation, a laser light emitting from the light source; a beam splitter disposed between the light source and the objective lens; a position sensitive device receiving the laser light emitting from the light source and having transmitted through the object requiring observation; and a position sensitive device receiving, through the beam splitter, the laser light reflected from the object requiring observation. To allow two-dimensional scanning, a pair of opposing galvanometric mirrors may be disposed at a pupil position between the beam splitter and the objective lens. An image processing and indicating means is connected to these position sensitive devices to make easy a simultaneous observation by a plurality of observers.
