Micro-optic adapters and tips for surgical illumination fibers
A microstructure optical adapter or tip according to the present disclosure may incorporate precision micro structure optical components engaging the input or output end of light energy delivery devices for customized light delivery of the light energy. The incorporation of precision micro structure optical components in injection molded plastic or glass parts will allow for inexpensive modification of the output light while also serving to protect the end of the illumination device. The micro structure optical components may also be incorporated in an adapter to tailor the light energy to the subsequent device.
