Glass Fresnel Lenses

Famous quotes containing the words glass and/or lenses:

    Our ideal ... must be a language as clear as glass—the person looking out of the window knows there is glass there, but he is not concerned with it; what concerns him is what comes through from the other side.
    Elizabeth Bowen (1899–1973)

    Life is a train of moods like a string of beads, and, as we pass through them, they prove to be many-colored lenses which paint the world their own hue, and each shows only what lies in its focus.
    Ralph Waldo Emerson (1803–1882)
