Optical sighting device

Abstract

An optical aiming device includes a light source module, a base, and a reflector. The light source module includes a light source and a substrate on which the light source is disposed. The base includes a first end and a second end disposed opposite to each other. The light source module is disposed on the base, with the light source of the light source module facing the first end. The reflector is disposed at the first end and has a first optical axis. Irradiated light emitted by the light source corresponds to the reflector within an illumination angle range, and the irradiated light within the illumination angle range is reflected by the reflector to form reflected light. The base further includes a light-emitting structure, which includes a through-hole. A portion of the irradiated light not reflected by the reflector faces the through-hole, and a portion of the irradiated light exits the base through the through-hole.
