Also called calcite. A natural hexagonal crystal of calcium carbonate. It cleaves readily into rhomboids useful in the study of polarized light.
ICF

iconometer
An instrument in which an object's image, produced by a lens of known focal length, is used to determine the object's distance from the instrument when its size is known, or the object's size if the...
iconoscope
A camera tube that employs a high-velocity electron beam to scan a photoemissive mosaic and to store electrical charge patterns.
ICP
induction-coupled plasma
ID
inside diameter
IDCA
integrated Dewar cooler assembly
IDDS
integrated double differentiated sampling
ideal crystal
A crystal that is devoid of any mosaic structure and that can reflect x-rays, relative to the Darwin-Ewald-Prins law.
ideal filter
Any filter in which the range of frequencies within a chosen radius suffers no attenuation and the range of frequencies outside the radius is entirely attenuated.
ideal polarization rotator
A theoretical instrument conceived of as a box that receives a beam of radiation of any arbitrary polarization angle and produces a new beam, coaxial with the incident beam, having a specified new...
ideal radiator -> blackbody
An ideal body that completely absorbs all radiant energy striking it and, therefore, appears perfectly black at all wavelengths. The radiation emitted by such a body when heated is referred to as...

identification friend or foe system
A system that transmits and receives identification codes to facilitate the discrimination between enemy and friend in a tactical situation.
idiochromatic
Pertaining to the possession of photoelectric characteristics as a result of the properties of the true crystal and not of foreign materials.

illuminance
Luminous flux incident per unit area of a surface; luminous incidence. (The use of the term "illumination" for this quantity conflicts with its more general meaning.)
illuminant
Source of radiation defined or specified by its spectral power distribution.
illuminant metamerism
Metamerism that occurs when the light source is changed.
illuminated
Characteristic of a surface or object that has luminous flux incident upon it.
