Tungsten-Halogen Light Sources

TH is a general light source for visible and NIR range spectroscopic applications. Tungsten-Halogen lamps are near blackbody sources of light with fused silica envelopes around the tungsten filaments and a small quantity of an active halogen gas such as Bromine. The TH light source provides very stable and smooth spectral output so it can be applied to spectroscopic measurements (transmittance/reflectance/absorption) and color measurements. The dominant spectrum is from 300nm to 2.6µm depending on the color temperature of each lamp (due to the deep absorption band and the natural transmittance of the fused silica envelopes, the IR range is limited to 2.6µm).
