DH-2000-BAL Deuterium Tungsten Halogen Light Source

Name: DH-2000-BAL Deuterium Tungsten Halogen Light Source for UV-Vis-NIR Spectroscopy
Brand: Ocean Optics
Availability: InStock

Description

The DH-2000-BAL Deuterium Tungsten Halogen Light Source is a broadband UV-Vis-NIR illumination system designed for spectroscopy, absorbance analysis, transmission measurements, fluorescence workflows, and analytical optical instrumentation requiring stable continuous spectral output across ultraviolet, visible, and near-infrared wavelength regions. By combining deuterium and tungsten halogen lamps within a single optical platform, the DH-2000 family delivers continuous broadband illumination spanning approximately 190–2500 nm for laboratory spectroscopy and OEM analytical systems.

Unlike standalone tungsten halogen sources that primarily emphasize visible and near-infrared output, or deuterium-only lamps optimized for ultraviolet measurements, the DH-2000-BAL integrates both illumination technologies to support spectroscopy applications covering multiple spectral regions simultaneously. The deuterium lamp provides strong ultraviolet output for UV spectroscopy and absorbance measurements, while the tungsten halogen lamp extends coverage into the visible and near-infrared regions for broadband optical analysis.

The integrated light source architecture supports stable optical output for UV-Vis absorbance spectroscopy, reflectance measurements, fluorescence analysis, optical sensing, and transmission spectroscopy. Easy-to-replace pre-aligned bulbs minimize downtime while maintaining repeatable optical performance during long-term laboratory operation. Select DH-2000 configurations additionally support deep-UV operation down to 190 nm for demanding ultraviolet spectroscopy applications.

Fiber-coupled SMA 905 connectivity enables straightforward integration with miniature spectrometers, optical probes, integrating spheres, fluorescence systems, and OEM spectroscopy platforms. Advanced models include integrated shutters, filter holders, and TTL control capabilities that support automated spectroscopy workflows and synchronized optical measurements.

The DH-2000-BAL series is widely used in analytical chemistry, biomedical optics, environmental sensing, industrial inspection, metrology, and advanced spectroscopy research requiring stable broadband UV-Vis-NIR illumination across a wide spectral range.
