Avantes BV has added the DH-Bal balanced deuterium/halogen light source to its AvaLight line of sources to extend the dynamic range of its AvaSpec spectrometers. The device eliminates the D-alpha line at 655 nm, which, for users of deuterium sources, tended to saturate detectors. It includes a shutter that can be operated manually or via transistor-transistor logic signal from a proprietary spectrometer platform. It can be used from 200 to 2500 nm and is available in a deuterium-only version. The intensity of the halogen part of the spectrum is adjustable. The combined technologies are suitable for spectroscopy applications such as reflectance, transmittance, absorption and fluorescence.
