Light SourcesOur DH-2000 Deuterium Tungsten Halogen Light Source combines the continuous spectrum of deuterium and tungsten halogen light sources into a single optical path for powerful output from 215-2500 nm. In addition, Deep-UV versions of our DH-2000 are available with a 190-2000 nm range.DH-2000 Deuterium Tungsten Halogen Light SourceOptions and Accessories: Shutter and Filter Holder Integrated shutters are available for your DH-2000 and can be driven by either a switch or a TTL signal.You can also include a filter holder with the source that accepts filters up to 4 mm in thickness and as large as 25 mm square or 25 mm round. The DH-2000 has an SMA 905 connector for easy coupling to our spectrometers and accessories via an optical fiber.Adjustable Power The DH-2000 has a potentiometer that adjusts the intensity of the tungsten halogen output. This allows you to adjust the optical power of the light source from 10-100%.Item CodeDescriptionDH2000-DUVUses a Deep-UV deuterium bulb that provides 190-2000 nm wavelength rangeDH2000-SIncludes shutter control via a TTL signal or manual switch up to 5 HzDH2000-S-DUVUses a Deep-UV deuterium bulb that provides a 190-2000 nm wavelength range; includes shutter control via a TTL signal or manual switch up to 5 HzDH2000-FHSIncludes a filter holder for filters up to 25 mm square or 25 mm round and 4 mm thickDH2000-FHS-DUVUses a Deep-UV deuterium bulb that provides 190-2000 nm wavelength range; includes a filter holder for filters up to 25 mm square or 25 mm round and 4 mm thickMeasured with HR2000+ Spectrometer with 25 m Slit and 400 m Optical FiberDH-2000 Series Spectral OutputSpecificationsDimensions: 150 mm x 135 mm x 319 mmWeight: 3.5 kgPower consumption: 25 W (deuterium); 20 W (tungsten halogen)Wavelength range: 190-400 nm (deep-UV deuterium bulb) 215-2500 nm (standard deuterium and tungsten halogen bulbs)Humidity: 5-95% without condensation at 40 CLamp current: Operating 85 V/0.3ALamp lifetime: 1,000 hoursLamp voltage: Ignition 580 V at 20 CCurrent voltage drift: 0.01% per hourCurrent voltage stability: 5 x 106 peak-to-peak (0.1-10.0 Hz)Operating temperature: 5 C - 35 CPower requirements: 85-264 V 50/60 HzRadiation characteristic: Aperture 0.5 mm, numerical aperture 26 (13); focused Total power: 100 WPower consumption: Approximately 78VAWarm-up time: 40 minutes (deuterium); 20 minutes (tungsten halogen)Markings: CE; VDI/VDE 0160; EN 61010Light SourcesD-2000 Powerful, Stable Deuterium Source for UV ApplicationsDeuterium Light Source The D-2000 Deuterium Light Source delivers robust, even output from 215-400 nm with peak-to-peak stability of less than 0.005% and drift of only +/-0.5% per hour. D-2000 is also available in a Deep-UV configuration that provides you a wavelength range of 190-400 nm.Technical Tip Ultraviolet radiation below 300 nm degrades transmission in silica fibers, resulting in solarization (increased light absorption in the UV fiber that can invalidate data). For applications using the D-2000 Light Sources, we recommend solarization-resistant assemblies.
