Improvements in medical research, clinical diagnosis and treatment outcomes rely on the wide availability of biomedical instruments that produce accurate test results rapidly and cost effectively. Thanks to advances in lasers and optics, flow cytometry has become an essential bioanalytical tool to analyze the immune or genetic characteristics of cells. Next generation flow cytometers can rely on the extremely stable, low noise, optical output power of II-VI’s QOMO laser head series to achieve optimum measurement sensitivity and accuracy. This speeds up the measurement throughput, an important factor in reducing cost. The QOMO lasers operate at 488 and 638 nm for dual-wavelength flow cytometry configurations. II-VI’s broad portfolio of products for flow cytometry includes optics and filters for fluorescence spectroscopy in the visible and ultraviolet wavelength ranges, as well as flow cells and precision air and fluid temperature control systems based on thermoelectric coolers.
