Lippmann Plate

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:

    The great social adventure of America is no longer the conquest of the wilderness but the absorption of fifty different peoples.
    —Walter Lippmann (1889–1974)

    I sometimes have the sense that I live my life as a writer with my nose pressed against the wide, shiny plate glass window of the “mainstream” culture. The world seems full of straight, large-circulation, slick periodicals which wouldn’t think of reviewing my book and bookstores which will never order it.
    Jan Clausen (b. 1943)
