Introduction to CMOS Image Sensors
CMOS image sensors are designed with the ability to integrate a number of processing and control functions, which lie beyond the primary task of photon collection, directly onto the sensor integrated circuit.

Fluorescence and DIC Combination Microscopy
Fluorescence microscopy can be combined with contrast enhancing techniques, such as differential interference contrast (DIC) and phase contrast illumination, to minimize the effects of photobleaching.

Comparison of Phase Contrast and DIC Microscopy
The most fundamental distinction between differential interference contrast and phase contrast microscopy is the optical basis upon which images are formed.

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 in o 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 in o intensity differences.
