Fiber optics coupled deuterium and tungsten halogen sources / Light sources
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
Fiber optics coupled deuterium and tungsten halogen sources summary
They are ideal for absorbance and reflectance spectroscopy.
A proprietary filtering technology option installed in BALANCE version produces a “smoother” spectrum across the entire wavelength range and eliminates problems associated with strong D-alpha line near 655nm, present in all deuterium bulbs.
These models have an integrated shutter that can be controlled by a TTL signal or a switch on the front panel. It allows the limitation of the exposure of the sample
