TILL Photonics Polychromatic Illumination System

Source: Applied Scientific Instrumentation
Polychrome II
  • High Output - unlike other monochromators and wavelength switchers, the Polychrome II delivers a bright (6-8mw), evenly illuminated field at the objective with a bandwidth of 15nm and a homogeneity of better than 5%.

  • High Speed - the Polychrome II has the ability to jump to any wavelength between 250 and 680nm in less than 3ms and provides a remarkable 1.5ms Fura jump between 340 and 380nm.

  • Easy to Upgrade - the modular design of the Polychrome II allows components to be easily added for complete imaging and photometric systems as well as uncaging flashes, D/A converters and other accessories. In fact, TILL Photonics has complete systems available for a wide range of applications including photometric, imaging and uncaging.

    The Polychrome II is the second generation of a rapidly tunable excitation source from TILL Photonics. The Polychrome II is comprised of a xenon light source, galvanometric scanner, mount grating and mirror optics. The monochromatic light is coupled to specially designed epi-fluorescent condensers via a solid quartz fiber. The specially designed condensers are available for most microscopes and provides for optimal illumination.
