SPECORD® 50 Powerful UV VIS spectrophotometer with double-beam mode due to SBT (Split-Beam Technology). The new concept behind the SPECORD 50 combines the high energy throughput of a single-beam spectrophotometer with the stability of a double-beam instrument. All this is due to the Split-Beam Technology (SBT). Unlike the classical double-beam spectrophotometer, by the far greater part of the source energy is used for the sample beam. Only a minor share of the radiation energy is branched off, via a beam splitter, and focused on a reference detector. From the two detector signals, the measuring system of the SPECORD 50 established the photometric result. This means that changes of the single-beam signal, due to variations in the light yield of the source, are compensated. Such variations may occur during source warm-up or ambient temperature changes.
SPECORD® 40 Robust single-beam spectrophotometers for spectral region from UV to NIR. The approved, versatile single-beam spectrophotometer for the measurement of 190-1100 nm conforms to Ph.Eur. quality.
