A laser-endoscope with direct beam coupling.
An optical element for direct laser-beam coupling into the observation optic of a rigid endoscope was developed. Using this coupling element every suitable endoscope can be modified into a laser endoscope which can be used for laser surgery e.g. in ENT and urology. The requirements for the endoscope and the optical coupling element are discussed.
