The Polychrome II from Applied Scientific Instrumentation Inc. comprises a xenon light source, galvanometric scanner, blazed grating and mirror optics. The monochromatic light is coupled to specially designed epifluorescent condensers via a solid quartz fiber. The unit delivers a 4- to 8-mW, evenly illuminated field at the objective and a bandwidth from 12 to 15 nm. Homogeneity is better than 5%, and the modular device can jump to any wavelength between 260 and 680 nm in <3 ms.
