Definition of dispersion (Light spectrum term)

Light can be dispersed or collimated as it enters the sample or spectrometer. Dispersed light includes beams that are directed in multiple directions, while collimated light includes only beams of parallel incidence.

To obtain free-space measurements, connect an Ocean Spectrodispersimeter accessory to the spectrometer. This captures a 180° field of view of the fiber optic. DispersIon Meters can also be used to capture the spectrum emitted by a plane. (Spectrometer accessories, CC-3-UV-S, diffuse reflective plastic sheet, so that the spectrometer can capture 180° scattered light, and the collected light conforms to Lambertian characteristics)
