Spares and accessories for SR Series Spectrometer
HL-2000-HP-FHSA Light Source
Ocean Insight offers sturdy, reliable tungsten halogen light sources to meet your application requirements. From high-power to long-lifetime models, our HL-2000 product family provides flexibility for your lab for measurements from 360-2400 nm.
All HL-2000 models have an integrated fan to keep source cool and stable, and a built-in holder that accommodates filters for conditioning the light. Some models include an integrated shutter and long-lifetime bulb. A universal power supply makes setup quick and easy.
DH-2000-BAL Light Source
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.
