A Range of Various UV/VIS Spectroscopy and Spectrophotometers

The property of reflection or transmission of a material as a function of wavelength by quantitative analysis of molecules is called spectrophotometry. The instrument used for the measurement of transmittance or absorbance of the material is called spectrophotometer.  It uses photometers to measure intensity of the light in terms of color/wavelength. Its working principle is based on  Beer-Lambert's Law. It can work in UV-Visible range. The components of a spectrophotometer includes a source (to generate polychromatic light), a monochromator (to filter  a single wavelength of light), a sample cell holder, a detector (to detect and amplify the output) and reader which can be connected to Computer or Printer.
