Device for coupling laser beams on biological tissues for medical applications, has first optical cone terminated by plane convex lens pair connected to second cone of greater cross-section

摘要

The device couples laser emissions, whose rays are fed via a bundle of optical fibres into an input coupling housing and collected by a conical frustum-shaped, expanding optical cone (8) whose expanding inclination angle corresponds to the opening angle of the laser beam at the optical fibre bundle end. The cone is terminated by a plane convex lens pair (10) connected to a second optical cone (9) of greater cross-section and with inclination angle corresponds to the convergence beam arriving via the lens pair.
