DH-2000
The DH-2000 Deuterium Tungsten Halogen Light Source combines the continuous spectrum of deuterium and tungsten halogen light sources in a single optical path.
The combined-spectrum light source produces a powerful, stable output from 215-2500 nm. In addition, deep-UV versions of the light source are available, providing a 190-2500 nm wavelength range.
Options and Accessories
Integrated shutters are also available with the DH-2000 and can be driven either by a switch or by a TTL signal. Another option is to include a filter holder with the system, which accepts filters up to 4 mm in thickness and as large as 25-mm square or 20-mm round in diameter. All versions of the DH-2000 have an SMA 905 Connector for easy coupling to our spectrometers and accessories via optical fiber, and a safety shutter for blocking the light when the fiber is not attached.
Adjustable Power
All versions of the DH-2000 have a potentiometer on the back of the light source to balance the light level between the deuterium and tungsten halogen light sources. This potentiometer allows you to adjust the optical power of the tungsten halogen light from 10-100%.
Optical Fibers
We recommend using our solarization-resistant optical fibers with all versions of the DH-2000.
DH-2000 Spectral Output
We recommend using our solarization-resistant optical fibers with all versions of the DH-2000.
This spectral output graph shows the output of the DH-2000 (red) at full power and the DH-2000 with the tungsten halogen at low power (pink), D-2000 (blue). The height of the deuterium atomic emission line depends on the optical resolution of the spectrometer.
