  • DIC Microscope Configuration and Alignment

    DIC components can be installed on virtually any brightfield transmitted, reflected, or inverted microscope, provided the instrument is able to accept polarizing filters and the specially designed condenser and objective prisms.

  • Fundamental Concepts in DIC Microscopy

    Through a mechanism different from phase contrast, differential interference contrast converts specimen optical path gradients into amplitude differences that can be visualized as improved contrast in the resulting image.

  • Brief Overview of DIC Microscopy

    In the mid-1950s, a French optics theoretician named Georges Nomarski modified the Wollaston prism used for detecting optical gradients in specimens and converting them into intensity differences.

  • Reflected Darkfield Illumination

    One of the most effective ways to improve contrast in the reflected light microscope is to utilize darkfield illumination. In reflected darkfield microscopy, an opaque occluding disk is placed in the path of the light traveling through the vertical illuminator so that only the peripheral rays of light reach the deflecting mirror.
