摘要
A laser line generation device includes a unitary lens structure and a laser emitter. The unitary lens structure includes an aspheric surface, a conical surface, and a side surface. The conical surface tapers inwardly toward the aspheric surface to an apex of the conical surface that is opposite an interior side of the aspheric surface. In operation, the laser emitter emits light rays toward the unitary lens structure, and the light rays pass through the aspheric surface into the unitary lens structure, reflect off of the conical surface, and exit the lens structure through the side surface. The light rays exiting the unitary lens structure may be substantially perpendicular to the light rays entering the unitary lens structure.
