  • Patent number: 6052236
    Abstract: The light source equipment is provided with a light source and an anamorphic single lens. The anamorphic single lens has different refracting powers in the x and y directions orthogonal to each other, and converts a light from the light source to a light beam in a required state. Farther the anamorphic single lens satisfies the following equation :0.3<2.multidot.fy.multidot.tan (.theta.y/2)<0.7fy>fxwhere fx is a focal length in the x direction, fy is a focal length in the y direction, and .theta.y is a half angular divergence of radiant intensity of the light in the y direction.
