    摘要: A sampler for taking a defined amount of sample of a fluid medium from a sample-taking site, with a tubular line, which can be brought into contact with the fluid medium at the sample-taking site, for conducting the fluid medium into at least one sample storing receptacle, with a pump. The pump moves the medium via the tubular line into the sample storing receptacle. A sequence control activates the pump, such that it dispenses the defined amount of sample into the sample storing receptacle. The pump is a rotary piston pump.

    摘要: A condenser arrangement for brightfield illumination and/or darkfield illumination for optical microscopes comprises in a housing basic optics having at least one lens, at least one front optics which can be inserted into the illumination beam path in front of the basic optics, and means for inserting the front optics into the illumination beam path of the microscope. A first swiveling arm and a second swiveling arm are swivelably arranged at the housing of the condenser. The first swiveling arm carries first front optics with a high aperture for brightfield illumination and the second swiveling arm carries second front optics for darkfield illumination. The two swiveling arms are arranged at a defined distance from the shared basic optics of the condenser in direction of the optical axis of the illumination beam path. An aperture iris diaphragm is provided on the object side in front of the basic optics and is opened when the cardioid optics are inserted. Further, a darkfield slide with an annular mirror element is provided on the object side at the housing. Operator's controls serve to swivel the two swiveling arms for moving the darkfield slide and for adjusting the aperture iris diaphragm.

At least one optical element in the form of a beam splitter module or beam splitters for laterally splitting off at least a first partial beam path is provided in the space between the objective and the tube lens in which the telecentric beam path is located. A tube lens is located at a suitable distance from the objective in each of these first partial beam paths. At least a second partial beam path is branched off from at least one of these first partial beam paths and a tube lens is located at a suitable distance from the objective in each of these second partial beam paths. The tube lenses arranged in the individual partial beam paths have the same focal length or different focal lengths.

    摘要: A semiconductor laser diode, and a method for producing the semiconductor laser diode, includes a waveguide being terminated by a back facet and a front facet and a front facet coating and a back facet coating having a reflectivity providing for controlled decoupling of light at the front facet from the standing lightwave in the waveguide. The front facet coating includes a stack of layers providing for a phase shift of the standing lightwave within the waveguide such that the intensity of the lightwave at the front facet, where the light is decoupled from the standing lightwave, has a relative minimum.
