xerography
A printing process of electrostatic electrophotography that uses a photoconductive insulating medium, in conjunction with infrared, visible or ultraviolet radiation, to produce latent...
xeroradiography
A printing process of electrostatic electrophotography that uses a photoconductive insulating medium, in conjunction with x-rays or gamma rays, to produce latent electrostatic-charge patterns for...
XYZ axes
Conventional coordinates for optical system analysis, the X-axis being the horizontal, the Y-axis the vertical and the Z-axis the optical axis of the system.
YAG crystal
A YAG crystal refers to a solid-state crystal made of yttrium aluminum garnet (YAG), which is a synthetic crystalline material. YAG crystals are known for their exceptional optical properties,...
Young's modulus
The constant equal to the unit stress divided by unit deformation, relative to all values and a substance's proportional restrictions.
Young's two-slit interference
The method by which Thomas Young in 1802 disproved Newton's corpuscular theory of light by the formation of interference patterns between two beams of light from the same source. This was produced by...
ytterbium laser
A ytterbium laser is a type of solid-state laser that employs ytterbium ions (Yb³?) as the dopant in the gain medium. These lasers are known for their high efficiency, broad absorption and...
Z-scan
A technique for determining the nonlinear optical properties of a sample material by moving the sample through a focused laser beam and measuring changes in the beam's characteristics, such as...
Zernike's phase contrast method
The introduction of a filter into an imaging system to implement a phase contrast for an intensity mapping of a pure phase image.
zero phase shift mirror
A mirror that supplies equal reflectance for both the S-polarization and the P-polarization of a laser for a defined angle of incidence, usually 45°.
zero-dispersion wavelength
In a single-mode optical fiber, the wavelength that causes material dispersion and waveguide dispersion to cancel each other. In a multimode fiber, loose term for the wavelength at which there is a...
zero-order filtering
The removal of the zero-order component of the Fourier spectrum distribution of an object with a small, opaque absorber or reflector in the Fourier plane, to produce images that appear bright on a...
Zerodur
Zerodur is a type of glass ceramic material known for its exceptional thermal and mechanical properties, particularly its low coefficient of thermal expansion (CTE) close to zero. It was developed by...
ZIF
zero insertion force
zip-cord
A two-fiber optical cable containing two single-fiber cables that are connected by a strip of jacket and that can easily be separated from one another for the installation of optical connectors.
zirconium arc
A small bulb containing a conducting gas, an arc being formed between a metal ring and a tiny zirconium electrode near the center of the ring. The heated zirconium emits light, and constitutes a...
zirconium fluoride
An infrared transmitting material used in the production of fluoride glasses for optical fibers.
zonal aberration
Spherical or chromatic aberration in a lens having a wide aperture. It is present because the refracting power varies for different zones concentric at the axis. This is the residual when the lens...
zone plate
A plate of glass, usually a photograph, on which there is a central spot surrounded by concentric annular zones, alternately opaque and transparent, the radii of the boundaries between the zones...
zoom lens
An optical system of variable focal length, the focal plane remaining in a fixed position. This result is achieved by moving some of the components of the system along the lens axis, other components...
