Ideal Uses
Navitar Video Fluorescent Scope
Navitar’s Video ZFL Scope is a Macro/Micro
fluorescent vision system that utilizes inter-
changeable professional fluorescent cubes
and internal focus to create an image compat-
ible with most existing camera systems. It is
a simple means of doing very sophisticated,
task oriented fluorescence without the ex-
pense and complexity associated with a fully
loaded research microscope.
Basic Components of Any Video
Fluorescent System
1. A
light source
emitting the wavelengths
required to cause the labeling dye to
fluoresce.
Two different remote light sources are
available, a halogen light for the longer
wavelengths, and a metal arc lamp for the
UV. LED illumination is currently under
development.
2. An
integrated cube
that optimizes per-
formance by stopping all but the desired
(excitation) wavelength from reaching
the object and then stopping all but the
fluorescing wavelength (emitting) from
reaching the camera. There is a multitude
of off-the-shelf cubes available depending
