Abstract
A light source unit of the present invention includes a light emitting device emitting light having a characteristic in which emitted light travels in a predetermined direction in which a uniformity in intensity distribution relative to an axis of the emitted light is high and an unstable direction in which a uniformity in intensity distribution relative to the axis of the emitted light is lower than that in the predetermined direction, the unstable direction being at right angles to the predetermined direction, an intensity transforming lens formed to control the intensity distribution in the predetermined direction and on which the light emitted from the light emitting device is incident, and a superposition transforming optical device formed to control the intensity distribution in the unstable direction by dividing the intensity distribution into a plurality of directions and superposing divided intensity distributions one on the other.
