Abstract
A light emitting module includes a semiconductor laser, a collimating lens for that collimates light beam output from the semiconductor laser, a prism pair including two substantially triangular-plate-shaped prisms, each passing the light beam between two end surfaces on both sides of one apex angle to refract the light beam, and the prisms being sequentially arranged on an optical path of the light beam in such a manner that the orientations of apex angles of the prisms are opposite to each other, and a rotary stage configured to hold the prism pair and to be rotatable about a rotation axis C extending in a prism thickness direction in such a manner that an incident angle of the light beam entering the prism positioned on the upstream side of the optical path is changed.
