The Jenapol U Interphako is a rare instrument.  It’s a full research polarizing microscope with an interferometer head that will split the image beam and recombine it in such a way as to produce interference fringes on the image.  Each fringe is one wave-length apart, so 551nm in white light.  By calibrating based on the fringes, one can measure refractive index with great accuracy.  This particular microscope was originally sold by Martin Microscope to Philips Fibers and eventually it was traded back to us by BP-Amaco (who bought Philips Fibers in the 1990’s).  No microscope manufacturer makes a Mach Zender interference  microscope anymore.  Leitz had a twin beam type in the 1970’s (photo), and Carl Zeiss Jena had several models in the 1980’s and 1990’s culminating in the Jenapol Interphako model.  In our part of the country, we mainly sold these microscopes to textile fiber manufacturers for refractive index / birefringence measurements of their fibers.  Those institutions include DuPont, Monsanto / Solutia, BASF, Hoechst Celanese, Philips, etc.  The most  highly respected university textile departments had or have these as well, including NC State, Clemson, GA Tech, and Princeton.  Other customers have found uses for Mach Zender Interferometry for biological specimens.  One was researching the refractive indices of fish eye lenses.  This microscope has been carefully refurbished to excellent condition and is offered with a new Jenoptik digital camera and i-Solution software included in the price.  Contact us for complete specifications.
