1. A light emitting device comprising:
a plurality of laser elements including a first laser element and a second laser element;
a case enclosing the plurality of laser elements, the case comprising a base, the base comprising:
a bottom portion having an upward-facing surface that supports the plurality of laser elements, and
a frame portion surrounding the plurality of laser elementes and having a lateral surface that intersects with the upward-facing surface,

wherein an opening extends through the frame portion, the opening configured to allow light emitted from the plurality of laser elements to transmit through the opening; and
a plurality of main lenses secured directly or indirectly over the opening of the case including a first main lens configured to collimate or converge light emitted from the first laser element and a second main lens configured to collimate or converge light emitted from the second laser element; wherein:
at least a first portion of the opening is disposed on a first imaginary line passing through a light emitting end surface of the first laser element and the first main lens, and at least a second portion of the opening is disposed on a second imaginary line passing through a light emitting end surface of the second laser element and the second main lens.
