Abstract: Embodiments are for a confocal microscope unit attached to a connection port of a microscope including: light sources which output irradiation light to a sample to be observed; photodetectors which detect observation light generated from a sample in response to the irradiation light; a scan mirror which scans the irradiation light on the sample and guides the observation light generated from the sample to the photodetectors; a scan lens which guides the irradiation light scanned by the scan mirror to the microscope optical system and guides the observation light focused by the microscope optical system to the scan mirror; a lens barrel to which the scan lens is fixed; an attachment portion which attaches the lens barrel to the connection port; and a movable portion which supports the lens barrel so that an angle of the lens barrel with respect to the attachment portion is changeable.

Abstract: A confocal microscope unit according to an embodiment includes: a first subunit which includes a light source, a pinhole plate, and a photodetector; a second subunit which includes a light source, a pinhole plate, and a photodetector; a scan mirror which scans excitation light output from the first and second subunits on a sample via a microscope optical system and guides fluorescence generated from the sample in response to the excitation light and focused by the microscope optical system to the first and second subunits; and a main housing which is attachable to a connection port and to which the scan mirror, the first subunit, and the second subunit are fixed, wherein the first subunit and the second subunit are disposed in the main housing so that incident angles of two excitation lights to the scan mirror are displaced from each other by a predetermined angle.
