Multi-Port Illuminator

Mightex’s Multi-Port Illuminator (MPI) enables researchers to add a Polygon Pattern Illuminator to their microscope for targeted illumination while keeping their original light source for epi-fluorescence or other wide-field stimulation. MPI can be used in any inverted or upright microscope (e.g. Leica, Nikon, Olympus and Zeiss), or on Mightex’s OASIS Macro/Micro/Implant systems.

Multi-port illuminator (MPI)


System-level drawing of a Polygon and widefield lightsource connected to the backport of an inverted microscope via MPI.


  • One port accepts a standard 3mm-core liquid lightguide to produce wide-field illumination
    • Customers can use their existing light source and light guide.
    • Mightex can also provide LED light sources.
  • The other port accepts Polygon to produce patterned illumination
    • Standard front tube should be removed from Polygon before inserting Polygon into MPI.
    • Both “E” and “G” models of Polygon are accepted. “D” model is currently not accepted. *Older infinity-path Polygon models need to be converted to C-mount version first.
  • Standard-size dichroic in interchangeable filter cube
    • Optional excitation filters can be installed in filter cube.
    • Holds one (interchangeable) filter cube at a time.

Application Examples

  • Use on an inverted microscope where the back port is already occupied by a traditional epi-fluorescence illuminator, for customer who wants to keep the fluorescence imaging capability.
  • Use on an upright microscope not equipped with epi-fluorescence illuminator. MPI allows for the addition of both wide-field and patterned illumination capabilities onto the microscope.
  • Use on Mightex OASIS Macro/Micro/Implant systems. MPI provides additional flexibility in system configuration.
