    Abstract: An apparatus for carrying out spectral analysis of optical radiation emitted from a light source (11) comprises a spectral detector (1) having an entrance aperture (10) for the radiation from thelight source (11), a first imaging optical component (11), a first imaging optical component (12), a diffraction grating (14) for wavelength dispersion of the radiation, order sorting means (131, 132) for separation of the spectral orders of the diffraction grating (14), a second imaging optical component (15), and a detecting unit (16) for registration of the light source spectrum divided into order spectra through the order sorting means (131, 132). The order sorting means (131, 132) comprise at least two refractive optical components manufactured from different material. The two refractive optical components (131 and 132) together with the diffraction grating (14) and the imaging optical components (12 and 15) produce a substantially uniform distribution of the order spectra on the detector unit (16). Favourably the order sorting means (131, 132), the diffraction grating (14) and the imaging optical components (12, 15) also co-act to produce a substantially stigmatic image of the entrance aperture (10) in at least one point on the detector unit (16).

    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.

    Abstract: A compact, high sensitive, multi-wavelength spectral analyzer capable of simultaneously obtaining a spectral distribution of extremely weak radiation such as bioluminescence, chemiluminescence, extremely weak fluorescence caused by excitation light, Raman scattered light, etc. with an extremely high luminosity and without wavelength scanning. The spectral analyzer comprises a spectroscope and a high sensitive one- or two-dimensional photodetector. The spectroscope includes an entrance slit, a collimator lens of high luminosity disposed such that a focal point of the collimator lens is coincident with the entrance slit to convert light emerging therefrom into parallel rays, a reflection diffraction grating that diffracts the parallel rays from the collimator lens to produce spectra, and an imaging lens that focuses the parallel rays diffracted by the reflection diffraction grating on an image plane thereof to form a spectral image. The photodetector is disposed on the image plane of the imaging lens.
