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.

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.

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.
