Abstract: There are provided a light guide, an electron ray detector, and a charged particle device that can improve light guiding efficiency of light generated in response to incidence of a detection ray. The electron ray detector includes: a light guide member extending in one direction; a first fluorescent substance layer provided on one end portion side of the light guide member and generating primary fluorescent light in response to incidence of a detection ray; a second fluorescent substance layer extending from one end to the other end of the light guide member and generating secondary fluorescent light in response to incidence of the primary fluorescent light; and a detection unit provided on the other end portion side of the light guide member and optically coupled to the light guide member.

Abstract: A reference body 1 includes: a support 10 provided with a first light passing portion 18, a second light passing portion 19, a first accommodating space 14, and a second accommodating space 15; a first fluorescent body 20 accommodated in the first accommodating space 14 and configured to emit first fluorescence in a second wavelength band when irradiated with first excitation light in a first wavelength band through the first light passing portion 18; a second fluorescent body 30 accommodated in the second accommodating space 15 and configured to emit second fluorescence in the second wavelength band when irradiated with second excitation light in the first wavelength band through the second light passing portion 19; and a light shielding portion 13 disposed between the first accommodating space 14 and the second accommodating space 15. In a case where a light amount of the first excitation light incident on the first light passing portion 18 and a light amount of the second excitation light incident on the second light passing portion 19 are equal to each other, a light amount of the first fluorescence emitted from the first light passing portion 18 and a light amount of the second fluorescence emitted from the second light passing portion 19 are different from each other.

Abstract: There are provided a light-emitting element, an optical detection module, a method for manufacturing a light-emitting element, and a scanning electron microscope using the same, by which it is possible to reduce crosstalk and expand the range of applications. A light-emitting element includes a fiber optic plate substrate having transparency to fluorescence and a light-emitting layer as a nitride semiconductor layer having a quantum well structure. In the light-emitting element, the fiber optic plate substrate and the light-emitting layer are directly bonded to each other.
