Spectrometer testing fees

Spectrometer, also known as spectrometer, widely known as direct reading spectrometer. Photomultiplier tubes and other light detectors to measure the intensity of the spectral line at different wavelengths position of the device. It consists of an incident slit, a dispersion system, an imaging system and one or more exit slits. A dispersive element is used to separate the electromagnetic radiation from a source into the desired wavelength or wavelength region, and the intensity is measured at a selected wavelength (or by scanning a certain wavelength band). Divided into monochromator and multicolor instrument two kinds.
