Abstract: A spectrograph with a first concave spectrographic diffraction grating is positioned to receive light from an input light source. The first concave spectrographic diffraction grating is configured to provide a diffracted light output dispersing the components of the input light source in a first dispersion direction with a first angular orientation with respect to the plane of the grating. The dispersion forms the input light into an intermediate spectrum. The intermediate spectrum is formed in a focal surface by the once diffracted light. A slit is substantially positioned on the focal surface. A second concave diffraction grating is positioned to receive once diffracted light from the slit and configured to provide a twice diffracted light output, the second concave diffraction grating dispersing the components of the input light source in a second diffraction direction with a second angular orientation with respect to the plane of the grating. The second dispersion angular orientation is different from the first dispersion angular orientation. The second dispersion forms the input light into an output spectrum.

Abstract: The invention relates to a method and a device for obtaining a low-noise optical signal.According to the method, a luminous beam is injected through two apertures and after detection respectively a basic optical signal (21) and a corrective optical signal (22) are generated. Both optical signals obtained (21, 22) are subtracted, so that a resulting optical signal is generated, forming the low-noise optical signal. The apertures are preferably two slits of a spectroscope, the optical signals being expressible relative to the wavelength.

Abstract: A spectroscopy method in which a sample is scanned without moving the sample. Light from the sample 16 is collected by a lens 14 and analyzed at a spectrum analyzer 28 before being focused onto a photodetector 32. Light from the focal point of the lens 14 is brought to a tight focus on the photodetector 32 whilst light from in front of or behind the focal point comes to a more diffuse focus. Light from the pixels on the photodetector 32 corresponding to the focal point of the lens 14 is processed, whilst light from pixels outside this region is ignored, thus forming a ‘virtual slit’. The sample 16 is scanned in a vertical direction by moving the ‘virtual slit’ up and down, by changing the designated rows of pixels from which data is analyzed. The sample is scanned in a horizontal direction by moving a vertical slit 24 in the light path in a horizontal direction.
