- Ultraviolet. the electromagnetic radiation with wavelengths shorter than about 400 nm and not visible to the human eye.
- Ультрафиолетовый
- Invisible electromagnetic radiation defined between 100 and 380nm.
- The part of the electromagnetic spectrum that falls just below visible violet. ultraviolet (uv) coating – a coating that blocks out uv radiation up to 380+ nanometers.
- Electromagnetic radiation in the wavelength range of 4 to 400 nanometers.

ultraviolet radiation | - Ultraviolet radiation (uv) is one form of radiant energy coming from the sun. the sun emits a range of energy known as the electromagnetic spectrum. the various forms of energy, or radiation, are classified according to wavelength (measured in nanometres (nm) where one nm is a millionth of a millimetre).
- Sunlight rays or short wave radiation from sources such as welding, lasers, or tanning lamps. uv light can damage the eyes and lead to snow blindness, cataracts and degenerative diseases of the eye.
- Electromagnetic radiation at wavelengths immediately below the visible spectrum, i.e., within the wavelength range 10 to 380 nm. may be classified as: far ultraviolet, 10 to 280 nm; middle ultraviolet, 280 to 315 nm; near ultraviolet, 315 to 380 nm. also may be classified as: ozone-producing, 180 to 220 nm; germicidal, 220 to 300 nm; erythemal, 280 to 320 nm; black light, 320 to 400 nm. in either method of classification, there are no sharp demarcations between the wavelength bands.
- Short invisible rays of ultraviolet light. abbr uvr
- Electromagnetic radiation with wavelengths between 40 and 400 nm. see also irradiance and uv-a.
- Electromagnetic radiation with wavelengths between 40 and 400 nm. see also near ultraviolet. uv: ultraviolet. v
- Electromagnetic radiation with wavelengths between 100 and 400 nm.
- Irradiance and uv-a. fluorescent nondestructive testing uses uv-a and safe exposure limits for ultraviolet radiation and blue light hazard are available through the american conference of governmental industrial hygienists.

ultraviolet radiometer | Meter, usually calibrated at 365 nm, used in fluorescent liquid penetrant and magnetic particle testing to measure output of ultraviolet lamp. |
|
ultraviolet rays | Usually referred to as “uv”. invisible rays given off by radiant energy (sun’s rays). over exposure to uv results in eye damage. |
|
ultraviolet resistance | Ability to retain strength and resist deterioration on exposure to sunlight. |
|
ultraviolet source | - Term for the device providing excitation energy for fluorescent materials.
- Uv-a radiation source. unified numbering system: alphanumeric system for identifying alloys according to a registry maintained by astm international and sae international.4 magnetic testing glossary 389 uv-a: electromagnetic radiation with wavelengths between 315 and 400nm. fluorescent nondestructive testing has historically used ultraviolet energy centered at 365 nm.
