Abstract: A particle sensor is provided. The particle sensor includes a light projector that projects light to a detection area. A light receiver receives scattered light. The scattered light is light from the light projector that has been scattered by particles in the detection area. A first support supports the light receiver. A second support supports the light projector and has a linear expansion coefficient different from a linear expansion coefficient of the first support. The first support includes a first placement region in which the light receiver is disposed and a second placement region in which the second support is disposed. The first placement region and the second placement region are located at different distances from at least one of an optical axis of the light projector and an optical axis of the light receiver.

Abstract: An illumination apparatus, which is to be connected to a light source apparatus that generates laser light and which is to be attached to an optical cable that guides the laser light, is provided. The illumination apparatus includes a light-emitting module which is to be attached to a tip portion of the optical cable. The light-emitting module receives the laser light emitted from the optical cable, converts the laser light into light having a different wavelength of a predetermined color, and emits the light. A heat dissipating lens case includes a lens and dissipates heat generated by the light-emitting module. The lens controls distribution of the light emitted by the light-emitting module. The heat dissipating lens case includes an attachment structure which allows the heat dissipating lens case to be removably attached to the light-emitting module.

Abstract: A lighting apparatus including a base is provided. The base includes a through-hole. The through-hole is aligned with an optical path of laser light for receiving and transmitting the laser light. A light emitter which, when irradiated with the laser light transmitted through the through-hole, radiates light by converting a wavelength of the laser light. An attachment component is provided on the base for attachment of the light emitter to the base. The light emitter is removable from the base. A light blocker opens the optical path of the laser light by being contacted by the light emitter when the light emitter is attached to the base, and blocks the optical path of the laser light when the light emitter is removed from the base.

Abstract: A light source device is provided. The light source device includes: a ferrule which holds an optical fiber; a light-emitting element which emits laser light; and a casing which houses the ferrule and the light-emitting element such that the laser light enters the optical fiber. The casing includes a through hole from a first end face to a second end face. The through hole includes a diameter which decreases in a stepwise manner from the first end face toward the second end face. The ferrule is fitted to a small bore portion of the through hole, which is smallest in diameter. The light-emitting element is fitted to a large bore portion of the through hole, which is larger in diameter than the small bore portion.

Abstract: An illumination apparatus which uses laser light emitted by a light source is provided. The illumination apparatus includes a housing which is tubular, internally includes an optical path for the laser light, and includes a first end surface having an opening through which the laser light passing through the optical path is released. A light emitter is opposed to the opening, receives the laser light released through the opening, converts the laser light into light having a different wavelength of a predetermined color, and emits the light. A cap is removably attached to a first end portion of the housing and through which the light emitted by the light emitter is released. A shutter opens the optical path when the cap is attached to the housing and closes the optical path when the cap is detached from the housing.
