Nightsea Xite Fluorescence flashlight system

View fluorescence in the lab or the field! The Xite Fluorescence Flashlight System includes single-wavelength fluorescence excitation flashlights available with any of the five wavelengths in the NIGHTSEA line, paired with matching barrier filter glasses for maximum viewing contrast. Genotyping your transgenic organisms, screening cell cultures, inspecting parts with fluorescent penetrants, finding fluorescing critters in the field, ... the Xite line provides what you need.The Xite flashlight system is replacing the Dual Fluorescent Protein (DFP) flashlight.  This had been our only option for flashlights with excitation wavelengths other than Royal Blue.The most popular DFP option was the combination of Royal Blue and Green LEDs, for excitation of GFP and red fluorescent proteins, respectively. The replacement would be the Xite-RB plus the Xite-GR. Note that the cost to purchase both of these lights is less than the price of the DFP.

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, etc.), 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 colour coded for the colour of the excitation light, not the colour of the emitted fluorescence.

Designation Excitation Barrier Filter Glasses
UV - Ultraviolet 360 - 380nm 415nm longpass
VI - Violet 400 - 415nm 450nm longpass
RB - Royal Blue 440 - 460nm 500nm longpass
RB-GO - Royal Blue, Green Only 440 - 460nm 500 - 560nm bandpass
CY - Cyan 490 - 515nm 550nm longpass
GR - Green 510 - 540nm 600nm longpass

With the Royal Blue (RB) excitation we offer two options for filter glasses - longpass and bandpass.
