DH-2000 Deuterium Tungsten Halogen Light Sources

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.

The DH-2000 is available for $3300. Additional DH-2000 models are available.

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

Measured with HR2000+ Spectrometer with 25 μm Slit and 400 μm Optical Fiber
