| titleOfInvention | Spectrophotometer and measuring head therefor |
| abstract | A spectrophotometer intended for installation comprises a measuring head with a lighting arrangement (10) having at least one light source (11) for illuminating a measuring object located in a measuring plane (M) at an angle of incidence of substantially 45 °, with a picking arrangement (20) for collecting the light from the measurement object remitted measurement light at an angle of incidence of substantially 0 ° relative to the Lot on the measuring plane, with an entrance slit (31) having spectrometer arrangement (30) for the spectral splitting of the collected and fed through the entrance slit measurement light and with a spectrally split measuring light acted upon photoelectric receiver assembly (32) for converting the individual spectral components of the measuring light into corresponding electrical signals. Furthermore, it comprises an electronic circuit (100) which controls the light source (11) and generates digital measured values from the electrical signals generated by the photoelectric receiver arrangement. The light source (11) is formed as a flat cosine radiator and arranged so that their main radiation direction is substantially parallel to the main beam (21) of the remitted measurement light and the center distance of the light source from the main beam of the remitted measurement light is substantially the same size as the distance Light source (11) from the measurement plane (M). The light source (11) comprises a combination of two or more light emitting diodes of different spectral characteristics arranged in one plane and preferably on a common carrier, the plane being oriented substantially parallel to the measuring plane (M). The spectrometer assembly (30) comprises a cup-shaped spectrometer housing (34) made of plastic with a substantially cylindrical shell (34a) and a removable cover (34b). In the spectrometer housing, a concave diffraction grating (35) is arranged coaxially with the cladding and rests on an annular shoulder (34c) formed on the cladding and preferably complementary to the diffraction grating. The cover (34b) presses the diffraction grating (35) against the annular shoulder (34c) with a defined force via a compression spring (36). The spectrometer housing (34), with its side opposite the cover (34b), is positioned on a printed circuit board (33) containing the entrance slit (31) and the photoelectric receiver arrangement (32) and fixed to the printed circuit board by a tension spring (37). The Aufpickanordnung (20) is mounted directly on the spectrometer housing (34) opposite side of the printed circuit board (33). |
