1. A scanning microscope unit attached to a connection port of a microscope including a microscope optical system to constitute a scanning microscope, the scanning microscope unit comprising:
a light source configured to output irradiation light to a sample to be observed;
a photodetector configured to detect observation light generated from the sample in response to the irradiation light;
a scan mirror configured to scan the irradiation light output from the light source on the sample and guide the observation light generated from the sample in response to the irradiation light to the photodetector;
a main housing in which the scan mirror is internally disposed;
a scan lens configured to guide the irradiation light scanned by the scan mirror to the microscope optical system and to guide the observation light focused by the microscope optical system to the scan mirror;
a scan lens housing to which the scan lens is fixed;
an attachment portion which attaches the scan lens housing to the connection port; and
a movable portion which supports the scan lens housing so that an angle of the scan lens housing with respect to the attachment portion is changeable, wherein
the scan lens housing is fixed to the main housing,
the movable portion is fitted into the scan lens housing, and
an outer surface of the movable portion is formed as a spherical sliding surface, and an inner surface of the scan lens housing is provided with a spherical sliding surface corresponding to the outer surface of the movable portion.
