摘要： A photodiode array spectrometer for determining the spectral composition of a plychromatic beam of radiation comprises diffraction means (10) which generate from the polychromatic beam a diffracted beam with a plurality of spatially separated diffracted rays of different wavelengths (.lambda..sub.1, .lambda..sub.2, .lambda..sub.3). A photodiode array (11) receives the diffracted beam whereby each photodiode intercepts a different spectral portion of the beam. A rotatable transparent plate (8) is provided in the beam path in front of the diffraction means (10) which, due to refraction of the beam upon entering and leaving the plate (8), permits to vary the direction of the beam impinging on the diffraction means (10) and therefore the direction of the diffracted beam in small steps depending on the angle of rotation of the plate (8). By the stepwise displacement of the diffracted beam across the photodiode array (11), a better sampling of the diffracted beam and therefore an improved spectral resolution is achieved. The invention can be used in the spectrometric analysis of a sample contained in a sample cell ( 5), whereby the sample cell is irradiated with polychromatic light from a light source (1).

The detector (50) comprises a light source (100) adapted to provide an output light beam (230) as the optical stimulus signal. The light source (100) comprises a plurality of light emitting elements (200, 200A, 200Z) each adapted to emit a light beam (210, 210A1, 210A2, 210Z1, 210Z2) having a respective wavelength, and a diffracting element (220). The plurality of light emitting elements (200, 200A, 200Z) are arranged that emitted light beams (210, 210A1, 210A2, 210Z1, 210Z2) impinging, on the diffracting element (220) are diffracted by the diffracting element (220) to form the output light beam (230).

摘要： An adjustable optical component, for example an optical slit having adjustable slit width, comprises a movable member for providing an optical function, for example a slit and/or a shutter, and resilient suspension elements for connecting the movable member to a frame. The essential parts of the movable member, of the resilient suspension elements and of the frame consist of microstructures which are made of a common base material. Preferably, these parts are manufactured from a silicon chip by a micromechanical technique comprising, for example, anisotropic etching. In the case of an optical slit, the movable member comprises a plurality of openings of different widths which constitute a step slit. In order to adjust different slit widths, the member is moved along a line parallel to the center line of the step slit, with the force for moving the member being applied at an opening. When the member is moved by an external force, the resilient silicon beams are bending and the bars are moving. The movable member has an integrated shutter position. A high reproducibility of the adjustment of the center positions of the openings constituting the step slit during repeated movement of the member is ensured.
