OpticsThe SpectroDirect is a single-beam spectral photometer. The light source is a tungsten halogen lamp with flash function. The lamp is switched on only momentarily during the measurement process*), so there is no need for a warm-up period. The SpectroDirect is ready to perform a self-test as soon as it is switched on. The light passes through an entry slot to the monochromator, where it is split into spectral ranges. The monochromator is a holographically produced, transparent grating. The movable mirror ensures tha |
