More Information
Summary:A collimation coupler of semiconductor laser used in the photodynamic therapy of eyeground for coupling the therapeutic light and the indicating light into a single optical fibre to coaxially output is composed of base plate, heat radiator, multiple semiconductor lasers, multiple collimation lenses relative to said semiconductor lasers, multiple optical way commutating elements, coupling lens, and optical fibre connector. Its advantages are simple and compact structure and high optical coupling efficiency.
