A dual-axis acceleration detection element comprises a first detection element, a second detection element and a stationary unit. The first detection element is movable relative to the second detection element. The second detection element is movable relative to the stationary unit.

Hence when the relative movements occur among the first and second detection elements and the stationary unit, overlapped areas of the detection electrodes change to generate and output a capacitance difference, thereby acceleration alteration can be detected.

Biochemical assays that are performed in cuvettes and in the wells of multi-well plates and that utilize excitation and light emission as labels for detection are enhanced by an illumination and detection system that supplies excitation light through an optical fiber that transmits excitation light from an excitation light source to the cuvette or well.

The optical fiber and collimating lens can either be on the same side of the receptacle (generally the open side) or on opposite sides, i.e., one above and the other below. When the optical fiber and the collimating lens are both on the open side of the receptacle, they are arranged such that the direction of travel of the excitation light and the direction along which the emission light is collected are not coaxial, and preferably both are at an acute angle to the axis normal to the mouth of the receptacle. Illumination systems are also disclosed in which a ultraviolet, visible, or near-infrared light source is optically coupled to an optical fiber.
