Abstract
A transmission type confocal laser microscope has a transmission side objective lens below a specimen stage, which comprises an objective lens unit which is movable in an optical axis direction and a fixed relay lens unit, wherein movement of the objective lens unit for focus adjustment will not change the optical path after the relay lens unit. The microscope further includes an optical path switch on an optical path in the rear of the transmission side objective lens for switching between the optical path to the concave mirror and another optical path; and a target in a position optically equivalent to the concave mirror, which is illuminated by a light source for adjusting the transmission side objective lens for focusing.
