Abstract: A spectroscope of the present invention includes a concave diffraction grating which disperses incident light, an incident light introduction unit which introduces incident light into the concave diffraction grating, and an outgoing light receiving unit which receives outgoing light dispersed for different wavelengths by the concave diffraction grating. The spectroscope further includes an incident aperture which limits an incident angle of light emitted by the incident light introduction unit to the concave diffraction grating, and an outgoing aperture which limits an outgoing angle of outgoing light dispersed for different wavelengths by the concave diffraction grating to the light receiving unit. The spectroscope is constructed so that relatively rotational transfer of at least two out of the concave diffraction grating, the incident aperture and the outgoing apertures can be performed along a Rowland circle which the concave diffraction grating forms.

A reflective grating such as a diffraction or holographic grating situated on the circumference of a Rowland circle along with a point of light emission and a detector may be a configuration of the spectrometer. Some configurations may use an external light source where the light may be optically conveyed to the point of emission on the circle. There may be a Raman configuration where an interaction of light with a sample or an interactive film of a channel in a fluid analyzer is the point of light emission for the spectrometer. In some configurations of the spectrometer, the grating and/or the film may be reflective or transmissive.

Abstract: In order to extend the available spectral range and to optimize spectral resolution while retaining a compact spectrometer setup, two diffraction gratings are operated with congruent focal curves in a Paschen-Runge geometry. The spectrometer features only one entrance slit and allows an adequate adaptation of the covered spectral range to the demands of analytical spectrometry. Apart from photomultiplier tubes commercial solid-state linear array sensors placed tangential at the Rowland circle are used for simultaneous detection of the spectrum. By employing angular cut cylindrical mirrors the radiation is deflected by 90% upward or downward in an alternating series. In this way two effects are achieved, an almost complete detection of the spectrum firstly and secondly a gain of intensity by focusing of radiation perpendicular to the plane of dispersion.

Abstract: The invention concerns an optical system for use in spectrometry and/or endoscopy, in which at least one probe is exposed to directional radiation produced by a radiation source, the radiation emanating from the probe is led to a spectrometer, in particular a simultaneous spectrometer, and/or an imaging device. It is proposed that the optical system should be provided with at least one control device with an radiation inlet surface and a radiation outlet surface; the control device should be provided with control elements held by a frame and capable of being displaced from a first position in such a way that the radiation energy transferred from the radiation inlet surface to the radiation outlet surface can be controlled while leaving the radiation outlet aperture substantially unchanged. In addition, or alternatively, the optical system is provided with at least one wavelength selection unit which has at least one dispersion element for spectral splitting of the radiation passing through at least one inlet slit and impinging on the dispersion element; and with at least one optical waveguide. The dispersion element and/or a focusing element focus the spectrally split radiation onto a focal surface and the optical waveguide receives a predetermined range of spectrally split radiation in the focal surface.

Abstract: A spectrograph usable as a demultiplexer/detector in a wavelength division multiplexing optical system. The spectrograph comprises a planar waveguide and a detector array. The planar waveguide has a dispersive edge having an inwardly concave shape, an input edge, and a straight output edge. The dispersive edge has a reflective diffraction grating formed on it, the grating having a variable line spacing. An optical input signal comprising a plurality of different wavelength ranges enters the waveguide at the input edge, and travels through the waveguide and strikes the grating. The grating focuses the optical energy in each of the wavelength ranges at a focal spot at the output edge, the position of each focal spot being a function of wavelength. The detector array comprises a plurality of photodetectors positioned along a straight line, such that the photodetectors are positioned at the focal spots. Each photodetector therefore detects the optical energy in one of the input ranges. A stack of such planar waveguides may be assembled to form a multi-channel spectrograph.
