    Abstract: PROBLEM TO BE SOLVED: To switch at least two types of observation methods, in observation methods of an optical microscope system, for example, such as bright field observation, dark field observation or differential interference observation. SOLUTION: A confocal laser scanning microscope acquires confocal images of a sample, and includes a laser optical system acquiring a confocal image of the sample, and an optical-microscope optical system which acquires non-confocal images of the sample by detecting measurement light coming from the sample. Then, the microscope includes a plurality of optical elements for differential interference, which can be respectively inserted and detached on optical axes of the laser optical system and the optical microscope optical system and which acquires a differential interference image of the sample by detecting the measurement light from the sample.

    Abstract: It is an object of the present invention to provide an optical beam scanning device and an image forming apparatus which suppress displacement of plural images formed by a different photoconductor in a sub-scanning direction by means of a simple structure even if temperature changes. The optical beam scanning device of the present invention has a single light deflecting device, a pre-deflection optical system that allows light beams from a plurality of light sources to enter the light deflecting device, and a post-deflection optical system including a first optical element for imaging reflected light beams from the light deflecting device on surfaces to be scanned for respective light beams. A second optical element, which has a positive or negative power opposite to a power of the first optical element in a sub-scanning direction, is provided in a position of the pre-deflection optical system where the light beams passes commonly and the light beams enter with distance in the sub-scanning direction.
