Abstract
A light emitting device includes: a laser element; a case enclosing the laser element, the case including a light-transmissive region configured to allow light emitted from the laser element to transmit through the light-transmissive region; a first lens configured to collimate or converge light emitted from the laser element; and a second lens that is disposed in the case and spaced apart from the first lens, the second lens located in an optical path between the laser element and the first lens. The second lens is spaced apart from the light-transmissive region such that an open space is located in the case between the light-transmissive region and the second lens.
