- The length of the light wave, usually measured from crest to crest, which determines its color. common units of measurement are the micrometer (micron), the nanometer, and the angstrom unit.
- The spatial period of a plane wave
- The distance between "waves" in the electromagnetic field, specified as angstroms or nanometers.
- The distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. wavelengths of light are measured in nanometers (10-9 m) or micrometers (10-6m).
- The linear distance occupied by one complete cycle of vibration of an energy form from any given point to the next point characterized by the same phase.
- For light waves or sound waves, the distance between two successive points of a periodic wave in the direction of propagation, in which the oscillation has the same phase; the distance the wave travels in one period. for light waves three common units of wavelength are: micrometer, nanometer, and angstrom. wave molding, oundy molding, swelled chamfer, undulating molding, undy

Near ultraviolet filter, английский
Device used to modify the emission spectrum from an ultraviolet radiation source by eliminating most visible light and high energy (far ultraviolet) radiation. nondestructive characterization (ndc): branch of nondestructive testing concerned with the description and prediction of material properties and behaviors of components and systems. nondestructive evaluation (nde): another term for nondestructive testing. in research and academic communities, the word evaluation is often preferred because it emphasizes interpretation by knowledgeable personnel. see also nondestructive examination; nondestructive inspection. nondestructive examination (nde): another term for nondestructive testing. in the utilities and nuclear industry, examination is sometimes preferred because testing can imply performance trials of pressure containment or power generation systems. nondestructive inspection (ndi): another term for nondestructive testing. in some industries (utilities, aviation), the word inspection often implies maintenance for a component that has been in service. nondestructive testing (ndt): determination of the physical condition of an object without affecting that object’s ability to fulfill its intended function. nondestructive testing techniques typically use a probing energy form to determine material properties or to indicate the presence of material discontinuities (surface, internal, or concealed). see also nondestructive evaluation; nondestructive examination; nondestructive inspection. o
Motion feedthrough, английский
Function provided by rotary or linear drives that penetrates the vacuum boundary to operate valve or pump or perform another function inside the vacuum system. see also vacuum grease. n ndc: nondestructive characterization. nde: (1) nondestructive evaluation.
