Phase Contrast Microscope Information What is phase contrast? Phase contrast is a method developed in theearly 20th century by frits zernike. (frits zernike biography). http://www.microscopeworld.com/high/phase-contrast2.htm
Extractions: Phase Contrast Microscope Information A common activity in high school biology is to observe cheek cells. To do this, one takes a flat toothpick and gently scrapes the inside of their cheek. They smear the specimen on a flat microscope slide and cover it with a cover slip. The cheek cells are epithelial cells and will be seen in large numbers. If you add a drop of iodine to the sample, the nuclei of the cells will become more visible. They will appear as small round dots inside the cell. In the first picture below, we see the cells as they would appear without iodine with a regular microscope. At the right, you see the same specimen using a phase contrast microscope (actually, we used the same microscope with different lenses). This clearly shows that, for some specimens, phase contrast will greatly improve your image quality. Image above with regular brightfield objectives. (click on image for larger picture) Notice the air bubbles at three locations, some cells are visible at the left side Same image with phase contrast objectives (click on image for larger picture) White dots inside each cell are the nuclei.
