What is Spectrophotometer or spectrometer?
This page covers Spectrophotometer or spectrometer basics.It mentions features of Spectrometer from reputed vendors/manufacturers. Other vendors of Spectrophotometer are also mentioned.
Definition: As we know in the field of physics, spectrometer is a instrument used to measure EM spectrum. The spectrum is a graph which has wavelength on X-axis and intensity on Y-axis. The spectrometer used in optical domain is known as spectrophotometer. It is used to measure light properties over specified range in the electro-magnetic or EM spectrum.
It has following applications:
• It is used in astronomy to analyze radiation from astronomical objects.
• It is also used to determine chemical composition.
