Deuterium Halogen Light Source TO-DH-LS

Thunder Optics DH-Light – Deuterium-Halogen Light Source

The Thunder Optics DH-Light is a high-performance composite light source that combines a continuous deuterium lamp and a tungsten halogen lamp in a single unit, providing seamless spectral coverage from 190 nm to 2500 nm (UV to NIR). Each lamp can be independently controlled, allowing users to adapt the output for a wide range of optical and spectroscopic applications, including absorbance, transmittance, and reflectance measurements.

Ideal for UV-VIS-NIR spectroscopy and compatible with high-precision analytical instruments such as liquid chromatographs, the DH-Light ensures excellent stability, long lifetime, and a robust thermal management system for sustained operation.

Key Features:

• Wide spectral range: 190–2500 nm continuous output

• Independent control of deuterium and halogen lamps

• Adjustable output intensity (tungsten halogen lamp: 0–100%)

• Efficient heat dissipation and long lamp lifespan

• Compact design: 201 × 150 × 110 mm, 2.5 kg

• Standard SMA905 or FC optical connectors

Technical Specifications:

• Deuterium lamp: 190–400 nm | 25W, lifespan ~1000 h

• Tungsten halogen lamp: 360–2500 nm | 5W, lifespan ~2000 h

• Output power (through 1000 µm fiber):
  – Deuterium: 171.6 µW
  – Halogen: 2.36 mW

• Warm-up time: 10 minutes

• Operating temperature: 5–35°C

• Power input: 85–250V AC, 50–60 Hz

• Energy consumption: ~78 VA

This light source is a versatile and reliable reference for any laboratory or research environment requiring broadband, stable illumination from UV to NIR.

⚠️ Safety Warning:

• Never look directly into the DH light source — it can cause serious and permanent eye damage.

• Do NOT open the unit. It contains no user-serviceable parts, and internal components operate at hazardous voltages.
