    • A focus detecting apparatus of the present invention comprises (a) an image projection unit which projects a first checking light through a first region out of two regions formed by splitting a space into two along a border plane including the optical axis of the objective optical system, onto the measured object to form an image of the light source thereon, and (b) an image detection unit which condenses a second checking light emerging from the image of the light source through the second region opposed to the first region with the border plane inbetween, on a light-receiving surface of a photodetector to form image of the measured object thereon. The image projection unit comprises a first converging optical system, which has a first refractive power in a first plane parallel to the border plane, which has a second refractive power substantially different from the first refractive power in a second plane parallel to the optical axis of the objective optical system and perpendicular to the border plane. The apparatus so arranged can be substantially free of influence of light scattering at a level-difference edge on the object surface and can maintain a high utilization factor of light, whereby it can detect the focus information of the objective optical system on the object with high accuracy.
