Description
The DH-2000-BAL uses innovative filtering technology to produces a smooth spectrum across entire UV-NIR range. This technology also eliminates the alpha deuterium line in the visible region. Using a combination of deuterium and halogen lamps, the DH-2000 is ideal for measuring a sample that has multiple features in different spectral regions or for analyzing a variety of different samples in your lab.
All deuterium sources have an alpha line, a sharp spectral feature centered at 655 nm. This feature and other deuterium lines produce “unbalanced” output in the deuterium and halogen sources. Simply adjusting the integration time of the spectrometer to suppress the alpha line does not solve the problem as the efficiency of the system at UV wavelengths drops significantly, compromising signal-to-noise performance.
Innovative filtering — eliminates D-alpha line in deuterium source
Balanced output from 210-2500 nm — eliminates problems associated with saturation
Powerful and stable — deuterium (25 W) and halogen lamps (20 W) combined in a single light source
Integrated shutter — helps protect light-sensitive samples
Easy-to-replace, pre-aligned bulbs — minimal downtime needed for bulb replacement
