Tungsten Halogen Light Source for VIS-NIR and NIR Spectroscopy

A tungsten halogen light source is used for spectroscopy applications such as absorbance, transmittance, reflectance, NIR spectral analysis, material testing and light source characterization.

The wavelength range depends on the lamp and optical design. Many tungsten halogen spectroscopy light sources are used in visible and near-infrared ranges. The actual range should be confirmed from the product specification.

A tungsten light source is mainly used for visible and near-infrared measurement, while a deuterium light source is mainly used for ultraviolet measurement. UV-Vis systems may use both lamps to cover a wider spectral range.

Yes. Tungsten halogen light sources are commonly used in VIS-NIR and NIR spectroscopy because they provide smooth broadband output in these regions.

A tungsten filament generates heat during operation. Cooling helps improve stability, reduce thermal drift and support longer measurement sessions.

Choose a tungsten light source according to wavelength range, output intensity, stability, cooling design, intensity adjustment, optical interface and compatibility with your spectrometer or measurement accessories.

Yes. A tungsten light source can be used for reflectance and transmittance measurement when paired with a suitable spectrometer, optical fiber, probe or sample holder.
