Abstract:
A cartridge and cartridge system for use in an apparatus for analyzing a sample is provided. The cartridge has one or more light sources and/or optical systems and other components that are specific for a certain type of application such as fluorescence, absorbance, or luminescence. The light source, optical systems, and other components for a specific application are housed in a single cartridge. The system has a plurality of cartridges for different applications for a multimode instrument. The cartridges are removably engaged with the apparatus in a “plug-in” format such that one cartridge may be removed from the apparatus and another cartridge may be easily installed.
Abstract:
A method and apparatus is disclosed for multi-mode spectral imaging. In one embodiment, the present invention comprises the steps of illuminating an object with a modified illumination profile, producing a reflected, transmitted or fluorescence image of the illuminated object, scanning the object, and re-imaging the reflected, transmitted or fluorescence light after modifying the light's optical state. The present invention preferably works in conjunction with other imaging systems to provide both high-spectral resolution images with lower temporal resolution and multiple image acquisition with high temporal resolution.
Abstract:
The present invention relates generally to the field of biochemical laboratory instrumentation for different applications of measuring properties of samples on e.g. microtitration plates and corresponding sample supports. The object of the invention is achieved by providing an optical measurement instrument for photoluminescence, chemiluminescence and/or AlphaScreen measurements wherein different optical modules are used for alternative measurements. The excitation pulses for the alternative measurements are guided via two different routes to optical modules, the routes reaching the module in different angles. This way it is possible to use alternative radiation sources without optical switches and without changing the optical system. The object of the invention is further achieved by providing an additional lens in the optical module when a thermo plate is used. This way it is possible to achieve a correct optical focus in different measurement modes not depending on the use of the thermo plate.
Abstract:
A system for the rapid characterization of analytes in saliva. In one embodiment, a system for detecting analytes includes a light source, a sensor array, and a detector. The sensor array is formed from a supporting member, in which a plurality of cavities may be formed. A series of chemically sensitive particles, in one embodiment, are positioned within the cavities. The particles may produce a signal when a receptor, coupled to the particle, interacts with the cardiovascular risk factor analyte and the particle-analyte complex is visualized using a visualization reagent. Using pattern recognition techniques, the analytes within a multi-analyte fluid may be characterized. In an embodiment, each cavity of the plurality of cavities is designed to capture and contain a specific size particle. Flexible projections may be positioned over each of the cavities to provide retention of the particles in the cavities.

Abstract:
A fluorescent auxiliary testing apparatus includes a light source module which emits a laser light to pass through a collimator, a dichroic mirror, and a first converging lens to project a testing object. The testing object emits a corresponding testing fluorescent light which passes through a filter assembly and a second converging lens and is received by a photo detector for generating a photoelectric signal. The photoelectric signal is transferred to a data processing equipment to perform test and analysis processes. The apparatus has a small size and a simple structure, and may be fabricated at a low cost.
