    Abstract: The invention relates to a Dyson-type imaging spectrometer that includes an input port (1) extending in a direction X, an output port, a diffraction array (4) including a set of streaks on a concave substrate, an optical system including a lens (2), said lens having a first planar surface (8) and a second convex surface (3), the convex surface of the lens and the concave surface of the diffraction array being concentric, wherein said optical system is capable of receiving a light beam from an input port and of directing the same towards the diffraction array, and of receiving a beam diffracted by the diffraction array and of forming a spectral image of said diffracted beam in a plane (7) of the output port, wherein said spectral image can be spatially resolved in an extension direction X’ of the image of the input port. According to the invention, the diffraction array (4) includes a set of nonparallel and non-equidistant streaks and/or the substrate of the diffraction array is nonspherical so as to form an image of the input port in the output plane having an improved image quality and very small distortions.

    Abstract: A volume diffraction grating having a substrate and an optically active layer has a structure formed in the optically active layer. The structure is operational to diffract optical signals in two selected spectral bands. The grating may be formed in a high dispersion embodiment suitable for separating individual signals from composite signals of both spectral bands. Alternatively, the grating may be formed in a low dispersion version which can separate the composite signals from each other. In another embodiment, a second structure is formed in the optically active layer. Each of the structures is configured to be operational in one of the spectral bands, allowing signals in each band to be diffracted independently of one another. In another embodiment, the structure (s) may have a curved profile allowing the diffracted beams to be shaped or focused without the need for external lenses.

    Abstract: A reflectometer (10) for measuring absorption of light in selected regions of the light spectrum by a diffuse reflector. The reflectometer (10) is adapted to precisely measure absorption resulting from the constituents present in body fluids. The sample (30) to be measured is illuminated by a focused light source (120) at an angle of 45° to its surface. The light diffusely reflected about the normal to the sample (30) falls on a small round bundle (200), the fibers are arranged into a narrow rectangle. This rectangle forms the entrance slit (230) for a concave holographic diffraction grating (230) spectrally separated over a flat field suitable for recording the spectrum on film or on an array of discrete detectors.
