DH2000 Deuterium Halogen Light Source
Product description
Deuterium and tungsten halogen light sources combine the continuous spectrum of deuterium and tungsten halogen bulbs into a single optical path that produce a stable spectral output from UV through NIR. They are ideal for absorbance and reflectance spectroscopy such as water quality monitoring, waste water analysis, marine chemistry, biological measurements, air quality monitoring and process control.
- For UV to NIR wavelengths
- High or low output power models available
- Continuous output for UV/VIS/NIR
- Adjustable relative intensity for the halogen bulb
- Internal shutter control via TTL signal or manual switch
