Many spectroscopic measurements require coordinated operation of detection instrument and light source, as well as data acquisition and processing. Integration of individual components can be challenging and applications may have different requirements. Conventional lamp-based tunable light sources are a popular choice for measurement systems with this degree of capability. Here’s a look at what you need to know to make the right choice. Consider smooth spectral output vs monochromatic throughput, constant current vs constant power, diffraction gratings, transmittance measurement, and measuring quantum efficiencies.
