Navitar’s Video ZFL Scope is a Macro/Micro fluorescent
vision system that utilizes interchangeable professional fluorescent cubes
and internal focus to create an image compatible with most existing camera
systems. It is a simple means of doing very sophisticated, task oriented
fluorescence without the expense and complexity associated with a fully
loaded research microscope.

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.
- An integrated cube that optimizes
performance 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 on which labeling dye is being used.
The Navitar system permits the usage of all standard Olympus BX2
Fluorescent Cubes, which are available from multiple sources. These are
captured singularly in a quick change holder requiring only a minute to
interchange. Information on filter sets and cubes can be found at

are adequate to handle the fluorescing light levels (which can sometimes
All other components are optics and mechanics that permit
variation of the magnification (field of view) and resolution, along with a
means of achieving critical focus.
Navitar System is Suitable for
Operation in Macro or Micro Mode
In the Macro mode, a fixed lens system provides up to a 9.2 mm diameter
field of view at a 165 mm working distance with a 2/3" format camera. A 6.5X
zoom accessory provides up to a 15 mm diameter field at a 108 mm working
distance. Various lens attachments allow the working distance to change from
32 mm to 165 mm. An add-on focus accessory provides a means of adjusting
focus without requiring a microscope type stand.
In the Micro mode, the same single lens system provides a 0.9X coupling of
any standard 200 mm tube length, infinity corrected, fluorescent microscope
objective to the camera.
