EMS Xite Fluorescence Flashlight System

Flashing mode for enhanced detection in ambient light

As bright as fluorescence may appear when you use an intense light source to view it in conditions of darkness, in most cases it actually tends to be a relatively weak effect that is easily masked by other light. If you try to find fluorescence when there is moderate ambient light (room light, sunlight, …), any fluorescing subject will respond to the excitation, but the response may be too weak to notice easily.

But there’s a trick – by making the excitation light source blink repetitively (a strobe effect), any fluorescence will blink at the same rate, while the illuminated background will not. This flickering increases the apparent contrast and thus increases detectability.

Available wavelengths

Wavelength sets are named and color coded for the color of the excitation light, not the color of the emitted fluorescence.

xite-UV– Ultraviolet	360 – 380nm	415nm longpass
xite-VI– Violet	400 – 415nm	450nm longpass
