IPC: G03B13/36
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To provide a focus detecting device which can detect focus excellently even if the pupil diameter of the objective of a microscope varies. SOLUTION: Optical detection surfaces of optical detectors 18 and 19 of the focus detecting device are divided into >=3 optical detection parts outwardly from the center.

When the pupil diameter of the objective is large, a focus error signal is found by using the difference between the sum of the output of the two inside optical detection parts 18a and 18b and the sum of the output of the more outside optical detection part 18c. Consequently, at least two kind of focus error signals can be obtained according to the pupil diameter of the objective, so a better signal can be selected and used.
