natural philosophy, physical science, physics - the science of matter and energy and their interactions

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

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; "refract a light beam"

resolve - make clearly visible; "can this image be resolved?"

aberrate - diverge or deviate from the straight path; produce aberration; "The surfaces of the concave lens may be proportioned so as to aberrate exactly equal to the convex lens"
