    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 instrumentation wherein a sample (281-285) is activated (212AS, 218AS) and the emission is detected (291, 292), wherein between the activation and detection phases of measuring the sample, a shift is made in the relative position between the sample and means (218) directing the activation radiation to the sample as well as in the relative position between the sample and the means (293) receiving the emission radiation from the sample. This can be implemented e.g. by moving (299) the sample assay plate and/or a measuring head between the activation and emission phases of a sample. The invention allows a simultaneous activation of a first sample and detecting emission from a second sample thus enhancing efficiency of the measurement.

    Abstract: A light amount is increased and an analyzing accuracy can be increased in accordance with an enlargement of a load angle.. However, scattered light tends to be loaded into a light receiving element in an analysis accompanied by scattered light, and the dynamic range of a concentration which can be measured becomes narrow. In the invention, light is dispersed by a light dispersing portion (20), a load angle of the received light is changed per wavelength, the load angle is made larger for light of a wavelength having a small light amount, and the load angle is made smaller for light of a wavelength having a large light amount and used for an analysis accompanied by scattered light. Accordingly, it is possible to gain a dynamic range of a concentration which can be measured in the analysis accompanied by scattered light, while increasing the light amount and maintaining the analyzing accuracy.

    Abstract: Light emitting diodes (LEDs) are mounted in an array to an upper structure overlying a lower structure with a plurality of light detectors thereon. Each LED is configured to overlie a separate detector. Each LED emits light at a frequency relevant for measuring optical density of a specimen. LEDs having different frequencies are included within the LED array. A corresponding array of detectors is also provided, mounted to the lower structure. Spacing between adjacent LEDs and between adjacent detectors match a spacing between wells in a microtiter plate. Spacing between the lower structure and the upper structure supporting the LEDs is sufficient for the microtiterplate to fit between. Circuitry sequentially fires individual LEDs and gathers optical density data through the detectors for specimens in the wells of the microtiter plate. The structures are then moved to a next adjacent well position on the microtiter plate and the process repeated.
