Abstract: The description relates to a standard for wavelength and intensity for spectrometers, particularly for calibrating and testing measurement heads in spectrometers which are usable primarily in the near infrared region (NIR) of the spectrum. The standard comprises a holder and a plate body arranged in the holder. The plate body is made of transparent plastic with high strength and dimensional stability over a large temperature range. The plastic has distinct absorption bands throughout the entire NIR range and has a chemical structure and composition ensuring an extensive moisture barrier against water absorption and water release in a reliable and stable manner over time. The plate body advantageously comprises an amorphous, transparent copolymer based on cyclic and/or linear olefins.

Abstract: In an arrangement to optically illuminate and/or to perform measurements in a sample stream through a flange which is arranged in the sample stream and closes off a hollow space against the sample stream, there is a continuous loss of material due to abrasion of wall particles, and the flange therefore has to be exchanged on a regular basis. The invention has the purpose of reducing the wear on the flange. To meet this objective, a part of the wall extending along a closed loop around the hollow space (3) consists of an elastomeric body (2.3). This concept makes it possible for the flange or at least for a part of the flange to elastically back away under a concentrated load. Thus, the rate of abrasion of the wall by the sample stream is reduced, because a large part of the incoming energy is converted to heat in the elastomeric body.

Abstract: The invention relates to a spectrometric assembly and method for determining a temperature value for a detector of a spectrometer. It is conventional to record the detector temperature in an optoelectronic detector using a thermal temperature sensor in order to compensate for temperature fluctuations. Due to the finite distance between the detector and the temperature sensor, the accuracy of the temperature detection is limited. According to the invention, the detector temperature should be recordable at high accuracy and with little effort. In addition to means for spectral division of incident tight and an optical detector for spectrally resolved detection of a spectral range of the divided light, a second optical detector is provided for detection of a partial range of this spectral range as a reference detector, wherein sensitivity of the reference detector is substantially temperature-independent.
