Abstract: A light detecting element is realized in which a length thereof is reduced in a direction perpendicular to a direction in which light detecting regions are disposed side by side. A light detecting element includes a light detecting surface provided with a plurality of light detecting regions disposed side by side in a first direction and a plurality of wiring regions electrically connected to the plurality of light detecting regions. Of the plurality of wiring regions, a plurality of the wiring regions connected to a plurality of the light detecting regions are provided in an end region that is a region excluding a central region at the light detecting surface.

Abstract: A light emitting device includes a base, a first light emitting element and a first light reflecting member disposed on the base and a lens member. The first light reflecting member is positioned with respect to the first light emitting element so that emitted light from the first light emitting element is divided into a portion of the emitted light from the first light emitting element irradiating onto the light reflecting face and a portion of the emitted light from the first light emitting element traveling outside of the light reflecting face by having an edge of the light reflecting face serve as a boundary. The lens member includes a reflected light passing region having a first lens shape configured to control the travelling direction of reflected light, and a non-reflected light passing region having a second lens shape configured to control a travelling direction of non-reflected light.

Abstract: A light emitting device includes a base having a bottom part, a first semiconductor laser element disposed on the bottom part of the base, and a first light reflecting member disposed on the bottom part of the base. The first light reflecting member has a light reflecting surface configured to reflect light emitted from the first semiconductor laser element. The light reflecting surface of the first light reflecting member is a curved surface configured such that, with respect to the major portion of the light emitted from the first semiconductor laser element, the beam divergence angle of the light reflected by the light reflecting surface is greater than zero and smaller than the beam divergence angle of the light irradiating the light reflecting surface.
