Aspheric Lens - Testing of Aspheric Lens Systems

Testing of Aspheric Lens Systems

The optical quality of a lens system can be tested in an optics or physics laboratory using bench apertures, optic tubes, lenses, and a source. Refractive and reflective optical properties can be tabulated as a function of wavelength, to approximate system performances; tolerances and errors can also be evaluated. In addition to focal integrity, aspheric lens systems can be tested for aberrations before being deployed.

Famous quotes containing the words testing of, testing and/or systems:

    In the gold mouth of a flower
    the black smell of spring earth.
    No more skulls on our desks
    but the pervasive
    testing of death....
    Denise Levertov (b. 1923)

    No testing has overtaken you that is not common to everyone. God is faithful, and he will not let you be tested beyond your strength, but with the testing he will also provide the way out so that you may be able to endure it.
    Bible: New Testament, 1 Corinthians 10:13.

    The skylines lit up at dead of night, the air- conditioning systems cooling empty hotels in the desert and artificial light in the middle of the day all have something both demented and admirable about them. The mindless luxury of a rich civilization, and yet of a civilization perhaps as scared to see the lights go out as was the hunter in his primitive night.
    Jean Baudrillard (b. 1929)
