    Abstract: A spectrometry instrument with exchangeable accessories (34, 48, 50, 52) providing, for example, different sample presentation facilities. The accessories include a manually operable cam-lock facility (54, 68) for quick and easy attachment of an accessory to the instrument. The instrument also includes an electrical circuit (86-90), which is completed by a circuit portion (100) in an accessory when the accessory is attached to the instrument, for generating a unique identifying voltage (94) to thereby identify that accessory. This allows for automatic loading in a controlling computer of programs for setting up and running the instrument for measurement regimes using that accessory. The spectrometry instrument is preferably a spectrophotometer used for phosphorescence decay measurements in which sequential phosphorescence emission measurements data from each of a number of excitation cycles applied to a sample are taken and then reassembled into a correct time sequence to define a phosphorescence decay characteristic for the sample, that is, measured data points from a second (and subsequent) excitation cycle are interleaved with those from a first excitation cycle. This significantly reduces the time for establishing a phosphorescence decay characteristic.

    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.

    Abstract: A coupling mechanism for mounting a sample accessory assembly into a spectrometer. The accessory assembly, on which is mountable a sample to be analyzed by a spectrometer, has connecter ends which are insertable into stirrups on the sample compartment of the spectrometer. The connector ends and the stirrups have elements that ensure that the accessory assembly is properly aligned in the sample compartment of the spectrometer. The accessory assembly also has an electronic component, such as a circuit or programmable microchip, that is connected to the spectrometer when the accessory is mounted in the spectrometer. The electronic component provides information to the spectrometer identifying the accessory assembly being used so that a diagnostic test of the spectrometer can be performed to ascertain, for example, proper mounting of the accessory assembly in the spectrometer.

    Abstract: Provided is a portable biosensor that includes a sample filter cartridge, a filter collector, an optical sphere, an electromagnetic radiation emitter, a photo-detector, a processor, a signal display, a vacuum pump, and a power supply. The sample filter cartridge selectively removes small molecules to minimize spectral interference in the detection signal. The sample is concentrated onto the filter collector and subjected to illumination by the electromagnetic radiation emitter, producing Raman-scattering. The optical sphere collects and distributes the Raman-scattering shifts, which then pass through a spectral filter to produce spectral filtered scattering, which is then reflected by the concave holographic flat-field grating onto the photo-detector. The data is displayed graphically to provide the Raman-scattering shift data. The data is compared with a database for sample identification. The device is contained within a housing that is small enough to be easily transported for field use.

    Abstract: An electromagnetic radiation spectrum detection system including a sensor device and an electronic control and processing module. The sensor device may include two photodiodes. The sensor device may convert an incident electromagnetic radiation (EMR) into electrical current. The electronic control and processing module may store numerical calibration values representative of a responsivity matrix of the sensor device. The electronic control and processing module may selectively provide the sensor device with electrical control voltage values (VB). The electronic control and processing module may process the values of detected electric currents (Iph) and the numerical calibration values to obtain spectrum information related to incident electromagnetic radiation spectrums. The electronic control and processing module may determine power spectral density of incident electromagnetic radiation.
