Abstract: A method of manufacturing an assembly to couple an optical fiber to an opto-electronic component includes providing the optical fiber having an end section with a front face to couple light in and out of the optical fiber, providing a housing to encase the end section of the optical fiber. The housing is formed with an opening to receive the optical fiber. The method further includes inserting the optical fiber in the opening such that the end section of the optical fiber is disposed inside the housing, attaching the optical fiber to a surface of the housing arranged to form a boundary of the opening, and aligning the front face of the optical fiber to the opto-electronic component.

Abstract: An optical fiber having an end section with a front face to couple light in and out of the optical fiber is inserted in an opening of a housing to encase the end section of the optical fiber. The optical fiber is attached to a surface of the housing, wherein the surface forms a boundary of the opening. The front face of the optical fiber is aligned to the opto-electronic device such that light coupled out of the front face of the optical fiber is coupled into the opto-electronic device or light coupled out of the opto-electronic device is coupled into the optical fiber at the front face of the optical fiber.

Abstract: A drag lever for actuating a gas exchange valve of an internal combustion engine. The drag lever includes an oblong lever body formed of sheet metal material, wherein the lever body has a bottom and side walls integrally formed at an angle of about 90° onto the bottom on both sides. A first end section of the lever body includes a joint socket formed into the bottom between the side walls. The joint socket serves to pivotally moveably support the drag lever on a joint head mounted stationary in the internal combustion engine. A middle section of the lever body is provided with a cam gripping surface, and a second end section of the lever body has a contact surface extending on the bottom. The contact surface serves for actuating the gas exchange valve. The lever body is dimensioned so as to have essentially the same width in a cross section through the joint socket and in a cross section through the middle section.

Abstract: An optical multi-pass cell (100) including a sample cavity (109) is provided. The cell (100) also includes first and second end mirrors (103, 104) positioned within the housing (101). The mirrors (103, 104) are configured to reflect a beam of light directed at one of the first or second end mirrors (103, 104) off-axis from the optical axis (113) one or more times between the end mirrors (103, 104) through the sample cavity (109) at a first distance from the optical axis (113) to create a first beam pattern (330). The cell (100) also includes one or more relay minors (220) positioned to intercept reflect the beam of light such that at least a second beam pattern (331) is created between the end mirrors (103, 104) at a distance from the optical axis (113) different from the first distance of the first beam pattern (330).

Abstract: In order to provide a non-stick coating which permits a very high coat thickness even under load, a polymeric matrix with embedded non-stick particles is used.

Abstract: An optical multi-pass cell (100) is provided. The optical multi-pass cell (100) includes a housing (101). The housing (101) defines a sample cavity (109) for receiving a sample under test. The optical multi-pass cell (100) also includes first and second end mirrors (103, 104) positioned within the housing (101). The first and second end mirrors are separated by a distance, L, and face one another coaxially to an optical axis (113) that extends between the first and second end mirrors (103, 104). The first and second mirrors (103, 104) are configured to reflect a beam of light directed at one of the first or second end mirrors (103, 104) off-axis from the optical axis (113) one or more times between the first and second end mirrors (103, 104) through the sample cavity (109) at a first distance from the optical axis (113) to create a first beam pattern (330).

Abstract: A method, element and system are provide for efficiently, accurately and without significant contribution of noise, splitting a beam of radiation or combining beams of radiation. In one embodiment of the invention, a beamsplitter front surface partially reflects incident radiation and refracts the rest of the radiation. The refracted radiation is completely reflected at a back surface of the beamsplitter and is completely refracted producing a parallel beam without creating any stray radiation or optical noise. This is accomplished using a p-polarized input beam and a Brewster angle geometry.
