A Lippmann plate is a clear glass plate (having no Anti-halation backing), coated with an almost transparent (very low silver halide content) emulsion of extremely fine grains, typically 0.01 to 0.04 micrometres in diameter. Consequently, Lippmann plates have an extremely high resolving power exceeding 400 lines/mm.

Famous quotes containing the words lippmann and/or plate:
“When distant and unfamiliar and complex things are communicated to great masses of people, the truth suffers a considerable and often a radical distortion. The complex is made over into the simple, the hypothetical into the dogmatic, and the relative into an absolute.”
—Walter Lippmann (1889–1974)
“Our press is certainly bankrupt in the “thrill of awe”Motherwise reverence: reverence for nickel plate and brummagem. Let us sincerely hope that this fact will remain a fact forever; for to my mind a discriminating irreverence is the creator and protector of human liberty.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
