    Abstract: A spectrometer includes an input unit for receiving an optical signal, a diffraction grating disposed on the transmission path of the optical signal for dispersing the optical signal into a plurality of spectral rays, an image sensor disposed on the transmission path of at least a portion of the spectral rays, and a waveguide device. A waveguide space is formed between the first and second reflective surfaces of the waveguide device. The optical signal is transmitted from the input unit to the diffraction grating via the waveguide space. The portion of the spectral rays is transmitted to the image sensor via the waveguide space. At least one opening is formed on the waveguide device, and is substantially parallel to the first and/or second reflective surface. A portion of the spectral rays and/or the optical signal diffuses from the opening out of the waveguide space without reaching the image sensor.

    Abstract: The invention concerns an optical system. The optical system comprises an input for receiving an optical signal, a predetermined output plane, and a diffraction grating for separating the optical signal received at the input into spectral elements thereof. The grating has a diffraction surface, which is formed by a photolithography process. The diffraction surface has a first predetermined profile. The first profile is formed by a plurality of points each conducted by different equations. Consequently, each spectral component is focused on the predetermined output plane.

    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.
