What's Included
  • Ocean Optics DH-mini UV-Vis-NIR Deuterium-Halogen Light Source
  • Ocean Optics QP400-2-SR-BX Solarization-Resistant Fibre Optic Patch Cord (400 µm, 2 m, SMA 905, Stainless Steel BX jacket)
  • 12 V DC Power Supply / AC Adapter (100–240 V input, universal)

The Ocean Optics DH-mini is a compact, high-intensity broadband light source combining a deuterium lamp and a tungsten halogen lamp in a single optical path, delivering stable output across the UV-Vis-NIR from 200 to 2500 nm. Designed for demanding spectroscopy applications including reflectance, absorbance, and transmission measurements, the DH-mini is equally suited to research and OEM integration. Its small footprint (75 mm × 82 mm × 175 mm) and low weight (0.5 kg) make it ideal for bench-top and portable setups alike.
