You use a spectrophotometer.
. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light

The spectrophotometer measures total cell count, including both live and dead cells.
A spectrometer shoots light through a sample and detects absorbance while a fluorimeter detects the intensity of fluorescence of a given sample.
Because we measure transmittance in spectrophotometer and for densely coloured samples transmittance will be very less. So we will not get proper results for absorbance.
A colorimeter can be used for that purpose.
A spectrophotometer is an instrument to measure how much light of a specified wavelength passes through a medium. It quantitatively measures the reflection or transmission properties of a material as a function of wavelength. The main uses of spectrophotometer are in the forensic sciences (including chemistry, biology, biochemistry, physics, etc.) as well as the medical field with the purpose being research.
