The Basics of UV-Vis Spectroscopy
www.agilent.comUltraviolet visible (UV-Vis) spectrophotometers use a light source to illuminate a sample with light across the UV to the visible wavelength range (typically 190 to 900 nm). The instruments then measure the light absorbed, transmitted, or reflected by the sample at each wavelength. Some spectrophotometers have an extended wavelength range, into the

assets.thermofisher.comIn a visible spectrophotometer, we shine a beam of light into a solution containing the sample, and detect how much of it comes out of the other side of the solution. By comparing the amount of light transmitted by the pure solvent to the amount transmitted when the sample is dissolved in it, we can calculate a quantity called the absorbance.

Microbiology: Methods for Counting Bacteria
mathbench.org.auOne way we can do this is to use a spectrophotometer. A spectrophotometer doesn't exactly count the bacteria, but it does. measure how much they interfere with a light beam, and based on that, we can use a standard curve to decide how many bacteria there are. Then we can do the scaling up trick to get the total population size.
