Abstract
A therapeutic laser radiation applicator including a laser energy radiator, a fresnel lens, and structure for mounting the fresnel lens in preselected association with the laser radiator for refracting a portion of the laser radiation to a preselected beam configuration adapted to provide a therapeutic tissue irradiation pattern. The support is preferably flexible to accommodate the applicator to the surface configuration of the tissue to be treated. The fresnel lens elements are preferably formed of a flexible material and, in the illustrated embodiment are formed integrally in a sheet of light-transmissive synthetic resin. The fresnel lens structure may comprise one or more fresnel lens elements in series light-diffracting relationship.
