Abstract: The solid immersion lens unit includes: a solid immersion lens having a contact surface allowed to be in contact with an inspection object and a spherical surface allowed to be opposite to an objective lens; a holder holding the solid immersion lens; a magnet provided to the holder; and a spherical body rotatably held by a magnetic force of the magnet at a position opposite to the spherical surface. The holder swingably holds the solid immersion lens in a state where the spherical surface is in contact with the spherical body.

Abstract: A spectrometry device includes: an integrating sphere which includes an inner wall surface and an attachment hole; an adapter which includes a guide hole guiding the measurement target light and is disposed in the integrating sphere; a plate which includes a first surface covering the guide hole from the outside of the integrating sphere and allowing a sample to be mounted thereon and a second surface and through which the measurement target light is transmitted; a holder which includes a concave portion mounting the plate thereon and is attached to the attachment hole; and a spectral detector configured to detect the measurement target light. The concave portion includes a bottom surface facing the second surface and a side surface surrounding the periphery of the plate. The bottom surface and the side surface are coated with a reflective material reflecting the measurement target light.
