ABSTRACT:
A probe microscope has a displacement detecting system formed of a spring element and a photodetecting element, the system being attached to a fine movement element, and a holder, which attached to the spring element fixed to the photodetecting system by a magnetic force, is moved by an alignment jig removably mounted on a sample moving stage in a three-dimensional fashion and a laser beam is converged on a selected point of the spring element with ease while confirming the state of alignment of the spring element with laser light based on an image produced by a camera and displayed on a monitor.
