What light source is used in most flow cytometers?

Posted August 3, 2022


The light source that is used in most flow cytometers are lasers. Laser light has a number of properties that make it the preferred option for use in flow cytometers. It is monochromatic, energetic, and coherent with a synchronized, identical wave frequency. These properties help to illuminate the cells with uniform light of a specific wavelength, which is essential for successful results.
