Principle of Spectrophotometer The spectrophotometer technique is to measure light intensity as a function of wavelength. It does this by diffracting the light beam into a spectrum of wavelengths, detecting the intensities with a charge-coupled device, and displaying the results as a graph on the detector and then on the display device. In the spectrophotometer, a prism (or) grating is used to ...
Spectrophotometry is a tool that hinges on the quantitative analysis of molecules depending on how much light is absorbed by colored compounds. Important features of spectrophotometers are spectral bandwidth (the range of colors it can transmit through the test sample), the percentage of sample transmission, the logarithmic range of sample absorption, and sometimes a percentage of reflectance ...
Visible light spectrophotometer – This type of spectrophotometer uses a visible light from a tungsten lamp. It is typically used for routine laboratory work, specifically the portable and bench-top spectrophotometer models.
A spectrophotometer, in general, consists of two devices; a spectrometer and a photometer. A spectrometer is a device that produces, typically disperses and measures light. A photometer indicates the photoelectric detector that measures the intensity of light. Spectrometer: It produces a desired range of wavelength of light.
