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.

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.

A control apparatus for a roof glass specifies the selection position of the selection switch when an output voltage from the selection switch is determined to be included in any of the allowable ranges predetermined respectively for the selection positions of the selection switch. The selection position of the selection switch is settled when the specified selection position has not changed even when a predetermined time passes after specifying of the selection position of the selection switch. When those selection positions which have been settled at a time of making the current decision and at a time of making a previous decision satisfy predetermined conditions, the roof glass is allowed to operate to a position corresponding to the selection position of the selection switch settled at a time of making a current decision.
