Researchers at the University of Arizona have designed a novel dark field illumination objective lens with a high numerical aperture.  The oblique illumination angles of this novel objective enhance contrast and reduce scattered light to help view objects whose refractive index is close to that of the surrounding medium. 



- biomedical imaging



- high illumination uniformity

- high numerical aperture 

Lead Inventor: Thomas Milster
