WebThe most common excitation light sources in flow cytometry instruments are lasers. Laser light is coherent (has a synchronized, identical wave frequency), monochromatic (has a single wavelength), and energetic—properties that ensure that the cells are illuminated with uniform light of a specific wavelength. WebLEDs present an alternative to lasers in LIF detection with CE, resulting in LED-induced fluorescence (LEDIF). LEDs are much less expensive, consume less energy and are more stable. In addition, LED light sources allow a greater range of wavelengths to better match the maximum wavelength for the flu …
