Fisheye Lens Conoscopy with the iPhone

LCMRC researchers,
motivated by a request
from one of the Center's
spin-off companies, have developed fisheye
lens conoscopy, one of the most significant
developments in the
characterization of
the birefringence of materials
in the last 150 years. Its implementation
with the iPhone camera makes optical
monitoring of polymer and liquid
crystal films in
application and
production particularly inexpensive
and uniquely powerful.
