| 摘要 |
The invention relates to a wideband hyperspectral spectrophotometer suitable for analysing an object (0), comprising: an illuminating assembly (S) comprising at least one source (Si) for emitting a light beam having a wavelength belonging to the ultra-violet domain in the direction of an object (0) to be analysed, said assembly (S) furthermore being configured to scan line by line the object (0) to be analysed by means of the emitting source (Si); a spherical focusing mirror (M2); a first redirecting mirror (M1) comprising a front face (M11) oriented toward the spherical focusing mirror (M2), said first face (M11) having a metal coating, the first mirror (M1) furthermore having a back face (M12) opposite the first front face (M11), said back face (M12) also comprising a metal coating, said first focusing mirror (M1) comprising in its centre a slit (F) configured to let pass a line of the beam emitted by the object (0); the first redirecting mirror (M1), the spherical focusing mirror (M2) and the slit (F) being arranged so that a fluorescent beam emitted by the object (0) after absorption by the object of the ultraviolet beam originating from the illuminating assembly is reflected from the first face (M11) of the first mirror (M1) toward the focusing mirror (M2), said focusing mirror (M2) then reflecting the beam thus focused toward the slit (F). |
