NIGHTSEA Fluorescence Excitation Flashlights, Barrier Filter Glasses


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.

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


NIGHTSEA Barrier Filter Glasses


The Royal Blue filter glasses are available in a choice of three styles. Styles 1 and 2 fit over eyeglasses, Style 3 does not. All other glasses colors are available in Style 2 only. Glasses meet ANSI Z87.1 impact standards for safety glasses. NOTE: Glasses Description refers to the excitation light source with which they are to be used.
