Medical instrument, particularly endoscope, for lighting- or therapeutic purposes, has radiation unit with radiation source in form of light-emitting diode, where windshield is arranged in radiation direction behind radiation source

摘要

The medical instrument has a radiation unit (6) which has a radiation source in the form of a light-emitting diode (8), where a radiolucent or partially radiolucent windshield is arranged in the radiation direction behind the radiation source. The windshield is formed from a material and has a refractive index, a higher tensile strength and hardness than optical glass. The windshield is formed from a synthetic monocrystalline crystal.
