Abstract: An apparatus for generating light having a plurality of wavelengths comprises a housing (1) and light sources (2) inside the housing (1). The light sources (2) are especially in the form of laser diodes. Preferably, three light sources having different wavelengths are formed. The apparatus further comprises collimating lenses (3) for collimating a light beam emitted by the light sources (2), and beam guiding elements for bundling the light beams. The collimating lenses (3) are disposed in a positioning module (4) that allows the collimating lenses (3) to be placed in different positions during the manufacturing process of the apparatus.

Abstract: A light module (1) which comprises preferably at least three laser diodes (2a, 2b, 2c) that emit light in a visible wavelength range, a respective collimating device (3a, 3b, 3c) per laser diode, a beam combination device (4) for combining the emitted light of the individual laser diodes (2a, 2b, 2c), a beam-shaping device (5) for shaping the combined beam, and at least one emitter (6) for generating non-visible light, in particular an IR laser diode. The emitter (6) is arranged in such a way that the emitted non-visible light is not guided through at least one of the beam combination device (4) or the beam-shaping device (5).

Abstract: A high-frequency transmission of data between functional units, which are mounted rotatably with respect to each other, of an endoscope, is permitted in which the functional units can be electrically insulated from each other. For this, an electric connecting element which, in a central flexible portion, is rolled up transversely with respect to the direction of transmission and is fastened by its respective end portions to the functional units is provided. An uninterrupted electrical connection with consistent quality of the signal transmission can therefore be obtained even when the functional units are rotated in relation to each other. By the rolling up of the central portion to form a winding, which is preferably configured in a self-supporting manner, a long term stable rotary degree of freedom is created in a very simple manner for the connecting element, with this degree of freedom permitting complex mechanical adjustment functions in the endoscope.
