    Abstract: The disclosure relates to an optical filter to be used for signal selection, removal of noise light, wavelength equalization of signal light, etc. in an optical communication, optical measurement or the like, and an optical amplifier employing such optical filter. Signal light is dispersed in different angles according to each wavelength by a diffraction grating and the dispersed light is selectively transmitted or reflected by a transmission type spatial filter or reflection type spatial filter, and is then coupled with an output fiber bundle as non-dispersed light by the diffraction grating. Thus, an optical filter capable of varying wavelength pass band characteristics and an optical amplifier uniform in wavelength amplification factor can be provided.

    Abstract: Les moyens de filtrage filtrent le rayonnement excitateur (EX) dans un premier sens allant des moyens générateurs (LS) vers l'échantillon (EC), en laissant passer une seconde bande spectrale (BZ) de largeur spectrale prédéterminée (l) et centrée sur une fréquence choisie correspondant à la longueur d'onde du rayonnement excitateur (λ0) et en arrêtant une première bande spectrale (FZ) complémentaire de la seconde bande spectrale (BZ), tandis que sensiblement simultanément à cette première opération de filtrage, lesdits moyens de filtrage filtrent en outre le rayonnement d'analyse (ON) dans un second sens inverse du premier sens, en laissant passer la première bande spectrale (FZ) et en arrêtant la seconde bande spectrale (BZ).

    Abstract: In optical detection system a plurality of photo-diode detectors are placed in an enclosure. The enclosure has an aperture through which is directed a light beam to be analysed. To eliminate the effect which ambient light entering the aperture would have one the detector signals, each of the detectors are arranged to be at equal distances from the aperture so that they all have the same acceptance cone angle for the light entering the aperture. Thus the ratio of signal to ambient light in the portion of the light beam reaching each detector is the same and the d.c. component of the signal produced by the detector can be easily removed in the signal conditioning electronics. The equal spacing of the detectors from the aperture is achieved in accordance with the invention by using beam splitters in the path of the beam to deflect portions of the beam to detectors which are offset from the beam axis.

    Abstract: An improved spectrophotometer, especially suitable for use in centrifugal analysis instrumentation, is disclosed. The spectrophotometer is improved by including therein a detector comprising a photodiode array assembly having a photodiode array, a spectral filter assembly situated substantially parallel thereto and in the path of incident light and means for attenuating stray light which would otherwise impinge on each of the photodiodes of the array.
