| differential display PCR | Method of image formation in the light microscope based on the method proposed by Nomarski (though strictly speaking all forms of optical microscopy rely to a greater or lesser extent on differential interference). The light beam is split by a Wollaston prism in the condenser, to form slightly divergent beams polarized at right angles. One passes through the specimen (and is retarded if the refractive index is greater) and one through the background nearby: the two are recombined in a second Wollaston prism in the objective and interfere to form an image. The image is spuriously three dimensional the nucleus, for example: appears to stand out above the cell (or be hollowed out) because it has a higher refractive index than the cytoplasm. The Nomarski system has the advantage that there is no phase halo, but the contrast is low and image formation with crowded cells is poor because the background does not differ from the specimen.

| eclipse | 1. <astronomy> An interception or obscuration of the light of the sun, moon, or other luminous body, by the intervention of some other body, either between it and the eye, or between the luminous body and that illuminated by it. A lunar eclipse is caused by the moon passing through the earth's shadow; a solar eclipse, by the moon coming between the sun and the observer. A satellite is eclipsed by entering the shadow of its primary. The obscuration of a planet or star by the moon or a planet, though of the nature of an eclipse, is called an occultation. The eclipse of a small portion of the sun by Mercury or Venus is called a transit of the planet. In ancient times, eclipses were, and among unenlightened people they still are, superstitiously regarded as forerunners of evil fortune, a sentiment of which occasional use is made in literature. "That fatal and perfidious bark, Built in the eclipse, and rigged with curses dark." (Milton) 2. The loss, usually temporary or partial, of light, brilliancy, luster, honor, consciousness, etc.; obscuration; gloom; darkness.
