摘要: The invention relates to a spectrometer, a spectrometric method and detector, and a new use of an interferometer. The spectrometer comprises a Fabry-Perot interferometer (120), to which light can be guided from the object (100) being investigated, in order to produce an interference image, and a detector (130) at which the interference image is aimed. The transmittance of the interferometer (120) is spectrally sliced to at least two separate wavelength bands. For its parts, the detector (130) is arranged to detect the interference image from at least two separate wavelength bands spatially. The detector is arranged to detect the said wavelength bands simultaneously, by exploiting the response of the image elements of the detector, calibrated as a function of the mirror gap of the interferometer, in order to detect simultaneously at least two different orders of the interference. With the aid of the invention, it is possible to implement spectrometric measurements more quickly, or to obtain more information on the object at one time.

摘要: The invention relates to a system and a method for optical measurement of a target, wherein the target is illuminated, either actively illuminated, reflecting ambient light, or self illuminating, and a measurement light beam received from the target or through it is detected. The prior art optical measurement systems generally include mechanical filter wheels and photomultiplier tubes, which cause the equipment to be expensive, large-sized and often not sufficiently accurate and stable. The objective of the invention is achieved with a solution, in which the illuminating light beam and/or measurement light beam is led through a Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers, and the Fabry-Perot interferometer or a set of two or more Fabry-Perot Interferometers is controlled into different modes during the measurement of a single target. The invention can be applied in optical measurements where, for example, reflectance, absorption of fluorescence of the target is measured.

摘要: The invention relates to a Fabry-Perot interferometer and a method for producing the same. More specifically, the invention relates to Fabry-Perot interferometers which are controllable with one or several actuators, such as piezoelectric, electrostrictive or flexoelectric actuators. In prior art technology there is a problem to achieve a sufficiently small and uniform gap between mirrors. In the present invention an intermediate structure (85a, 85b, 95a, 95b, 81a, 81b, 91a, 91b, 98a, 98b) is used between a mirror and an actuator or between two mirrors. The method of production also includes measuring the width distribution of the gap in several phases, and providing pre-actuation of actuators.

摘要: A capacitive vacuum measuring cell has a first housing body and a membrane, both of Al2O3 ceramic or sapphire. The membrane is planar with a peripheral edge joined by a first seal to the first housing body to form a reference vacuum chamber. A second housing body of Al2O3 ceramic or sapphire opposite the membrane, is joined to the peripheral edge of the membrane by a second seal to form a measurement vacuum chamber. A port connects the vacuum measuring cell to a medium to be measured. At least in the central area of the first housing body, an optical transparent window is formed and at least the central region of the membrane has an optically reflective surface. Outside the reference vacuum chamber, in opposition to and at a distance from the window, an optical fibre is arranged for feeding in and out light onto the surface of the membrane.
