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.

Abstract: Provided is a cooling unit to be used in an inspection of a semiconductor device. The cooling unit includes a jacket for dissipating heat of the semiconductor device. The jacket is provided with a light passing portion for passing light from the semiconductor device. The jacket has a space defining surface that faces the semiconductor device and defines a space between the space defining surface and the semiconductor device in a state where the light passing portion faces the semiconductor device. The jacket is provided with a supply flow path through which a fluid to be supplied to the space flows.

Abstract: A solid immersion lens holder includes a first member having a first opening disposing a spherical face portion therein so that a part of the spherical face portion protrudes toward an objective lens side and a second member having a second opening disposing a contact portion therein so that a contact face protrudes toward a side opposite to the objective lens side. The first member includes three protrusion portions extending from an inner face of the first opening toward a center of the first opening and configured to be contactable with the spherical face portion.
