The multiwavelength illumination system from TILL Photonics is a monochromatising device with an integrated light source.

High Output - unlike other monochromators and wavelength switchers, the Polychrome IV delivers a bright (6-8mw), evenly illuminated field at the objective with a bandwidth of 15 nm and a homogeneity of better than 10%.

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

The Polychrome IV is the third generation of a rapidly tunable excitation source from TILL Photonics. It is comprised of a xenon light source, galvanometric scanner mounted grating and mirror optics. The monochromatic light is coupled to specially designed epifluorescence condensers via a solid quartz fiber. These condensers are available for most microscopes and provides optimal illumination.
