Tunable Incoherent Light Sources

A conventional lamp-based tunable light source produces monochromatic light with wavelengths that range from the UV to the NIR. Tunable light sources (TLS) find use in applications requiring coordinated operation of a light source and a detection instrument with data acquisition and processing. The TLS is versatile, being both a broadband and high-resolution monochromatic light source which makes it suitable for applications such as the study of wavelength-dependent chemical or biological properties and wavelength-induced physical changes in materials. These light sources can also be used in color analysis and to measure the reflectivity of materials for quality purposes. The key components of a lamp-based TLS are a highly stable incoherent light source and a monochromator. Arc lamps and QTH lamps are commonly used in a TLS.
