ABSTRACT:
A light source package includes a light source, a lens for collimating the light from the light source, and a support member for supporting the light source and the lens so that the optical axis of the lens is set to a desired position relative to the light source. The support member includes a compensating device for compensating the lens for deviation of the optical axis of the lens resulting from a difference in the coefficients of linear thermal expansion between the lens and the support member when the ambient temperature changes.
