    摘要: In order to produce an improved coupling between waveguides of different refractive indexes, provision is made of a connecting device for connecting at least two optical waveguides (5, 6), in the case of which a first optical waveguide (5) is held relative to a second optical waveguide (6), an end face (7, 71, 72) of the first waveguide (5) running obliquely to the optical axis (11) of the first waveguide (5), and an end face (8, 81, 82) of the second waveguide (6) running obliquely to the optical axis of the second waveguide (6). In this case, the refractive index of at least one light-guiding region of the first optical waveguide (5) differs from the refractive index of a light-guiding region of the second optical waveguide (6), and the optical axes of the first and the second optical waveguides (5, 6) are arranged substantially parallel to one another.

    摘要: In order to meet the legal requirements regarding color of light from a headlight, especially at the light-dark boundary and how much scattered light can occur in the dark region, a lens (5) is provided, which has a diffractive structure on at least one of its surfaces (8). This lens (5) is built into a headlight with a diaphragm (4) arranged between the lens (5) and a light source (3) so that the diffractive structure is arranged substantially only in a region of the lens surface that is not masked by the diaphragm. In various embodiments a computer-generated hologram (17a-17e) can be arranged in the other region of the lens surface that is masked by the diaphragm, so that the lighting apparatus can perform other functions, such as improving driver visibility, displaying an image, measuring the distance to an object or detecting rain or snow.

    摘要: The invention relates to a compact lens with fixed or variable focal length for digital image acquisition. According to the invention, a refractive optical element of the lens or a group of elements on a light entry side of the lens is provided as a compound lens having a first lens element from a glass or optical ceramics with a first index of refraction and a second lens element from a plastic with a second index of refraction which is smaller than the first index of refraction, the first lens element being located on the beam path in front of the second lens element and on a light entry side of the lens. The lens also comprises at least one diffractive optical element. With a compactly built lens, imaging errors can thus be minimized by simple means. The diffractive optical element directly on or at a transparent cover is preferably made or provided for covering the detector array. Another aspect of the invention relates to a digital image acquisition device with such a lens.
