Polarizer Rotation in DIC
Microscopy of the
Silicon Zoo

Entries in the Silicon Zoo are photographed under conditions of differential interference contrast (DIC) illumination with a retardation plate in the light path.

This tutorial explores how polarizer rotation affects image color and contrast during examination of integrated circuit surfaces. To operate the applet, use the slider to simulate rotation of the polarizer in the DIC light path. As the slider is moved, the color characteristics and contrast of the image is varied in a manner dependent upon the surface properties of the integrated circuit. A radio button controls addition and removal of the retardation plate from the pathway. The pull-down menu allows visitors to select from a range of different samples.
