The DH2000-Mini Deuterium-Tungsten Fiber Optic Light Source is a compact broadband illumination source covering the 200–2500 nm spectral range, providing continuous output from the ultraviolet (UV) through the visible (VIS) to the near-infrared (NIR).

The system integrates a 3.8W deuterium lamp for UV illumination and a 1.2W tungsten-halogen lamp for visible and NIR wavelengths. Each lamp can be independently switched on or off to optimize measurements for different spectral regions.

An integrated shutter supports manual or TTL control, enabling precise light output management during automated measurements. The standard SMA905 fiber interface allows seamless integration with spectrometers, integrating spheres, optical fibers, and customized optical measurement systems.

Designed with an aluminum alloy and stainless-steel enclosure, the DH2000-Mini combines high stability, long lamp lifetime, and compact portability for laboratory, research, and industrial spectroscopy applications.
