Overview

DH2000 | Deuterium halogen integrated light source

Product Details

High quality and long-life scientific research wideband light source from ultraviolet to near-infrared

The DH2000 composite light source provided by Wenyi Optoelectronics for laboratory applications integrates continuous wideband spectra of deuterium and tungsten halogen lamps in one channel. The integrated spectrum provides continuous output from the 190nm to 2500nm wavelength range.

The continuous spectral range emitted by deuterium lamps ranges from 190-400 nm in the ultraviolet band to 400-800 nm in the visible light band, making deuterium lamps a high-precision light source for analytical and measuring instruments, such as those used in liquid chromatographs.

The light emission principle of tungsten halogen bulbs is achieved by utilizing the principles of heat emission and thermal radiation of objects. Tungsten halogen bulbs provide sufficient current to the filament, which heats up to incandescent state and emits light. The wavelength range of tungsten halogen bulbs is usually between 360nm-2000nm. The lifespan of tungsten halogen bulbs is related to their operating temperature. The higher the color temperature, the shorter the lifespan.

DH2000 features:

·Experimental grade high stability, high-quality deuterium and tungsten halogen lamps.

·Efficient cooling system.

·Provide continuous output of 190-2000 nm continuous spectral radiation.

·High power output can achieve balanced spectral output of deuterium halogen lamps, and the spectral intensity of halogen lamp output can be adjusted (adjustment range: 0~100%).

·SMA905 standard interface output.

·Deuterium lamps and tungsten halogen lamps can be turned on separately.

·Long lifespan and high stability.

·Suitable for UV spectroscopy measurement.

DH2000 matching fiber:

We suggest that you use Wenyi Optoelectronics' anti UV quartz fiber, especially when you need to use the wavelength band below 300nm. Since quartz also has absorption below 300nm, it is necessary to perform UV aging treatment on its quartz fiber. You can use our - XSR series fiber optic cables.

Optional accessories:

During the experiment, if the light output from the light source is too strong, causing saturation of the detection equipment, a fiber optic attenuator is needed. The fiber optic attenuator produced by Wenyi Optoelectronics Company can uniformly attenuate the optical signal, and the attenuation ratio is continuously adjustable from 0 to 100%.
