As the need for more personalized medicine increases, researchers are finding that new laser wavelengths and integrated multiwavelength laser light engines are enabling high-dimensional...
While laser wavelength and power are obvious critical parameters, there are numerous other factors to consider when specifying an optical microscope illumination system.

These total internal reflection fluorescence microscopy images were obtained using two excitation lasers combined in the Coherent Galaxy laser combiner; as part of research on the binding of actin filaments, the red signal is from Cy5-labeled Tm1A (protein) fluorescence excited at 640 nm, and the green signal is due to Alexa488 labeled actin excited at 488 nm.
