    Abstract: The method and apparatus of the present invention provides a system wherein light-emitting diodes (LEDs) (162) can be tuned within a given range by selecting their operating drive current in order to obtain a precise wavelength. The present invention further provides a manner in which to calibrate and utilize an LED probe (150), such that the shift in wavelength for a known change in drive current is a known quantity. In general, the principle of wavelength shift for current drive changes for LEDs is utilized in order to allow better calibration and added flexibility in the use of LED sensors, particularly in applications when the precise wavelength is needed in order to obtain accurate measurements. The present invention also provides a system in which it is not necessary to know precise wavelengths of LEDs where precise wavelengths were needed in the past. Finally, the present invention provides a method and apparatus for determining the operating wavelength of a light-emitting element such as a light-emitting diode.

    Abstract: Bekannte Messanordnungen zur ortsverteilten Erfassung von Spektren sehen ein zentral angeordnetes Spektrometer vor, mit welchem an verschiedenen Orten aufgestellte Messköpfe über Lichtwellenleiter kommunizieren. Hierbei stellen bei größeren Anlagen die Kosten der hierfür benötigten Lichtwellenleiter, die jeweils von einem Messkopf direkt zum Spektrometer verlegt werden müssen, eine große Investition dar. Die vorliegende Erfindung soll eine Möglichkeit vorstellen, diese Kosten erheblich zu reduzieren.
    Dies gelingt durch einen Messkopf mit einem Multiplexer, der eine Reihenschaltung mehrerer Messköpfe ermöglicht. Hierdurch kann eine parallele Führung von teueren Lichtwellenleitern vermieden werden und es wird vielmehr nur eine Verbindung von einem zum nächsten Messkopf von den Lichtwellenleitern zu überbrücken sein.

    Abstract: The present invention relates generally to the field of biochemical laboratory. More particularly the invention relates to the improved and more accurate instrumental features of equipment used as e.g. fluorometers, photometers and luminometers. The object of the invention is achieved by providing an optical measurement instrument where there is an interface (218, 223, 233a, 233b, 238) for a changeable optical module (240), and excitation and/or emission beam is guided through an aperture of the optical module. This allows performing various types of measurements by changing an optical module without a problem lenses becoming unclean due to manual handling of the optical modules. The invention also makes possible to achieve an accurate measurement location and area within a sample.
