What is a Continuous Wave?

Most common lasers generate a continuous, uninterrupted beam of light. These are called continuous wave lasers. They often have stable power and intensity. Some lasers are pulsed such that the light, and thus the energy, is only present for a short amount of time,...

What is Background Spectrum?

A background spectrum is a spectrum taken of experimental conditions without the sample of interest present. This captures background sources of light, such as room lights. It is not the same as the dark spectrum, which is the spectrum with no light present. However,...

What is a Dynamic Range?

The dynamic range of a spectrometer is a measure of the intensity resolution of a spectrometer. In essence, it is the maximum signal before saturation over the minimum signal, where the minimum signal is a signal equal to the baseline noise (S/N = 1). However, the...
