Flow Cytometry

Flow cytometry is a technique that uses lasers to excite single cells in suspension and detect their scattered light and fluorescence signals. It is widely applied in immunology, oncology, stem cell research, and clinical diagnostics. As the core light source, lasers must deliver high spectral purity, superior beam quality, and stable output to ensure accurate measurement. Backed by over 20 years of industry expertise, YESWEHAVE’s VisiStable^® Fiber-Pigtailed Diode Laser is designed to meet these requirements.

In flow cytometry, visible lasers—such as blue, green, and red—are well matched to the excitation spectra of commonly used fluorochromes, enabling reliable multi-channel detection. Modern high-end cytometers typically integrate 3–5 laser lines to achieve multiparameter analysis, and YESWEHAVE’s Fiber-Pigtailed Laser Diode provides the stability, beam quality, and spectral purity required for these demanding applications.

Moreover, RGB Diode Lasers and RGB Combiners, which merge red, green, and blue beams into a single optical path, offer significant advantages by simplifying optical alignment, reducing system footprint, and enhancing stability—making them especially valuable for compact and portable flow cytometers.
