Photonics Dictionary

A diode with a semiconducting material, such as germanium or silicon, for one electrode, and a fine wire "whisker'' which lies on the semiconductor, as the other electrode. The low capacitance...

crystal field

The electrostatic field acting locally within a crystal as a result of the microscopic arrangement of atoms and ions in the lattice.

crystal filter

A bandpass filter with piezoelectric crystal components for the passage or impedance of electrical signals of various frequencies.

crystal grating

A crystal that may serve as a diffraction grating if mounted effectively.

crystal laser -> solid-state laser

A solid-state laser is a type of laser that uses a solid gain medium (as opposed to a liquid or gas) to produce coherent light. The term "solid-state" refers to the fact that the active medium, where...

crystal lattice

A regular, periodic, geometric array of points corresponding to the positions of the atoms in a perfect crystal.

crystal optics

The study of the transmission of radiant energy through crystals, especially anisotropic crystals, and their effects on polarization.

crystal oscillator

An oscillator that uses a piezoelectric crystal to control its frequency.

crystal oven

A temperature-controlled container used to stabilize the temperature and resonant frequency of a crystal found in a crystal-controlled oscillator.

crystal quartz

The naturally occurring crystalline form of silicon dioxide. It is slightly birefringent and exhibits rotary dispersion of light rays transmitted along the crystal axis, both right-hand and left-hand...

crystal spectrograph

A system that applies a crystal as a diffracting agent to photograph the spectrum.

crystal spectrometer

A device designed to measure crystal properties by analysis of crystal diffraction.

crystall

crystalline

crystalline axes

The axes of symmetry in a crystal structure. See also biaxial crystal; uniaxial crystal.

crystalline lens

The internal lens of the eye. It is semielastic to permit changes in its power when focusing on objects at near distances.

crystallite

A small region within a single crystal where the molecules form a perfect lattice.

crystallized glass

Glass of special composition that is melted, formed into desired shapes, and subjected to a high-temperature treatment in which the glass undergoes a stage of nucleic formation, and a second stage,...

crystallogram

The photographic record of the diffraction pattern formed when x-rays pass through a crystal.

crystallography

The analysis of the atomic structures within crystals by means of x-ray diffraction.

Composite Symbology

csc

cosecant of

CSMA/CD

carrier sense multiple access/collision detection

CSP

channeled substrate planar

CSS

conical scan sensor

computed tomography; chemical transfer; center thickness

CTD

charge-transfer device

CTE

charge-transfer efficiency; coefficient of thermal expansion

CTH

chromium thulium holmium

CTLM

charge-transfer light modulator

CTR

current transfer ratio; cloud-top radiometer

cubic

cube-corner prism -> corner cube

A corner cube, also known as a corner reflector or retroreflector prism, is a type of optical device used to reflect light or electromagnetic waves back towards their source with minimal deviation in...

CubeSat

A CubeSat is a type of miniaturized satellite characterized by its standardized size and modular design. CubeSats are typically used for scientific research, technology demonstration, educational...

cubic convolution

A method of resampling in which a 16-pixel neighborhood around a given pixel from the original image is used to calculate the final brightness value of that pixel in the corrected image.

cup bevel

A bevel produced by grinding with a cup-shaped tool.

Curie temperature

The temperature above which a ferromagnetic material becomes only paramagnetic.

curie

Standard maintained by the International Commission on Radiological Units as a unit of radioactivity defined as the quantity of any radioactive nuclide in which the number of disintegrations per...

curing

The use of chemicals or radiation to induce a desired change in a substance; e.g., some optical adhesives are set by exposure to ultraviolet light and are said to be UV-curing.

current saturation

A condition during laser operation when laser output can no longer be increased by additional electric current.

current transient

A sudden, brief increase in current or voltage in a circuit that can damage sensitive components and instruments. Preventive measures include slow-starter circuits, filtering and static control.

cursor

On a display monitor, a small, mobile rectangle, cross-hair or pointer that locates a feature in an image that is the object of attention, or indicates where the next character will appear in word...

curvature

The measure of departure from a flat surface, as applied to lenses; the reciprocal of radius. Applies to any surface, including lenses, mirrors and image surfaces.

curvature loss -> macrobend loss

In an optical waveguide, that loss attributable to macrobending. Macrobending usually causes little or no radiative loss.

curvature of field

A lens aberration that causes a flat object surface to be imaged onto a curved surface rather than a plane.

curvilinear distortion

A lens aberration in which the focal length varies radially outward from the center of the field. It has the effect of making a straight tangential line in the object appear curved in the image,...

custom optic

A custom optic refers to an optical component that is designed, manufactured, and tailored to meet specific requirements or applications. These optics can include lenses, mirrors, prisms, filters, or...

cut plane

In computer graphics, intersection of a plane with a three-dimensional object to create a sectional view.

cutback technique

A technique for measuring fiber attenuation or distortion by performing two transmission measurements. One is at the output end of the full length of the fiber. The other is within 1 to 3 m of the...

cutoff wavelength

1. In detector technology, the long wavelength at which detector response falls to a set percentage (usually 20 or 50 percent). 2. In fiber optics, the shortest wavelength at which a fiber transmits...

cuton wavelength

In filter terminology, that wavelength where the filter transmission increases beyond 5 percent.
