Abstract
A range finder capable of adjusting light flux includes a light-emitting element configured to emit a light beam, a lens element, a light-shielding element configured to adjust light flux, and an image sensor. The light beam emitted by the light-emitting element is reflected by an object, passes through the lens element, and is projected to the image sensor. The light-shielding element is disposed between the object and the image sensor, and on a path of the light beam.
