optics

Noun
  1. The branch of physics that studies the physical properties of light (synset 106110385)
    associated with:
    • meniscus - (optics) a lens that is concave on one side and convex on the other
    • stigmatism - (optics) condition of an optical system (as a lens) in which light rays from a single point converge in a single focal point
    • astigmatism, astigmia - (optics) defect in an optical system in which light rays from a single point fail to converge in a single focal point
    • collimate - adjust the line of sight of (an optical instrument)
    • refract - subject to refraction
    • reflect - show an image of
    • resolve - make clearly visible
    • aberrate - diverge or deviate from the straight path; produce aberration
    • bifocal - having two foci
    • aplanatic - free from or corrected for spherical aberration
    • apochromatic - corrected for both chromatic and spherical aberration
    • aspheric, aspherical - varying slightly from a perfectly spherical shape
    is a type of: natural philosophy, physics - the science of matter and energy and their interactions
    subtypes:
    • catoptrics - branch of optics dealing with formation of images by mirrors
    • holography - the branch of optics that deals with the use of coherent light from a laser in order to make a hologram that can then be used to create a three-dimensional image
  2. Optical properties (synset 104957203)
    "the optics of a telescope"
    is a type of: property - a basic or essential attribute shared by all members of a class
