Visible Spectrometer

The VS series spectrometer is a very high-speed visible spectrometer marketed by Spectraline Inc. The spectrometer is used for analysis of a wide range of phenomenon that involves radiation in the visible wavelengths (300-1000 nm).

Operating Principle

Radiation enters the inlet port of the spectrometer through a window mounted on the front. The radiation goes through some optics including a set of prisms that separate the spectrum into its component wavelengths. The dispersed beam falls on a parabolic mirror that reflects it on to a detector array. The detector has a scan rate of 20 kHz. The signal from the detector is transmitted to a data acquisition board and is stored for display and analysis. The spectrometer comes with a DAQ system with VisiSpec software installed. The VisiSpec software calculates the relative intensities corresponding to the voltage of each pixel; and, plots it against the corresponding wavelength falling on each pixel. When referenced with calibrations obtained using a black body radiation source, the software provides the absolute values of radiation intensities recorded by the detector array.
