WitrynaOptical spectrometers are the most common type of spectrometer. They take light, separate it by wavelength and create a spectra which shows the relative intensity of these separate wavelengths. This basic principle has a wide range of applications and uses. Broadly speaking, all optical spectrometers consist of an entrance slit, a … Witryna3D imaging. This method is useful for nondestructive and noncontact analysis of each layer in multilayer films or buried foreign matter. The confocal optical system enables Raman imaging of the sample’s depth to be obtained. Polystyrene particles on Si wafer. (green: polystyrene particle, blue: Si) WitrynaFor this reason, HSI is often referred to as imaging spectroscopy. 1. As a quick aside, a spectrometer collects wavelength information as well as relative intensity information for the different wavelengths detected. 2 These devices typically collect light from a singular source or location on a sample. A spectrometer can be used to detect ... in cold blood book audio
