Abstract: An apparatus (100) for collimating a light ray field (1), a diode laser, the use of a collimation lens system (1), a collimation method and a method of producing a collimation apparatus. The apparatus (100) collimates a light ray field (L), which diverges more quickly in a first direction (F), perpendicular to the emission direction(s), than in a second direction (S), perpendicular to both the emission direction(s) and the first direction (F). The apparatus (100) comprises at least one first collimation lens system (1) for collimating the light ray field (L) in the first direction and at least one second collimation lens system (2) for collimating the light ray field in the second direction. The first collimation lens system (1) comprises a glass cylindrical lens (3) with an at least partly circular profile (4). The first collimation lens system (1) comprises an aspherical plastic lens element (5).
Abstract: A device for collimating a light radiation field of a light source (L) having a beam characteristic which is different in a first plane (FAC) from that of a second plane (SAC). The device comprises at least one first collimating lens (10) and a second collimating lens (20). The device has an additional optical element (30) in order to collimate the light radiation field in different planes to the first and to the second plane.

Abstract: Apparatus (1) for generating a light beam via at least first and second light sources (2, 3). During operation, the light sources (2, 3) emitting light at the same wavelength. The light sources are arranged such that the beam profile (11) of the first light source is rotated relative to the beam profile (12) of the second light source by a rotation angle (D) about an axis (A) in the direction of propagation. A beam rotation element (4) is located downstream of at least one of the light sources, which causes the beam profile (11, 12) to rotate such that the beam profile (11, 12), after passing through the beam rotation element (4) in a plane perpendicular to the direction of propagation (A) of the light, is oriented substantially identically to the beam profile of the other light source (2, 3) in the plane perpendicular to the direction of propagation.
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).
