nanometer (nm)
a standard unit of distance used in measuring wavelengths in the electromagnetic spectrum (equal to 10-9 meter or 10 angstroms); one billionth of a meter.
nanosecond
one billionth of a second.
Nanometer
A measure of Wavelength. Formula: Nanometer = a millionth mm.
Natural Light
Nature's illumination: daylight, even on interiors. The term implies that the source is not artificial.
The wavelengths of visible light corresponds to hundreds of nanometers (billionths of a meter). Wavelength is an important way to characterize a wave. For light, the shorter the wavelength, the higher the energy of the light wave.
This ultra-low refractive index coating is called "Nano Particle Coating" because the size of the particles that compose this coating ranges from a few nanometers to just more than 10 nanometers.
The wavelengths of light are so small that they are measured in nanometers (nm). A nanometer is equal to one millionth of a millimeter. Wavelengths of light range from about 400nm to 700nm in length and travel in a straight-line path.
Simple sheet or uncorrected molded glasses do not compensate for the 250 nanometer difference in the wave lengths of the red-cyan filters.
Modern photographic materials are available with sensitive to a wide portion of the spectrum, ranging from 250 nanometers (ultraviolet) to 925 nanometers (infrared). There are many applications for the selective use of this spectrum.
IR Infra Red Light is a frequency of light which is lower than the human eye's visible spectrum (in the range of 850 ~ 950 nanometers). Color cameras CANNOT use infrared light whatsoever.
Ultraviolet Photography refers to the branch of photography that captures pictures using ultraviolet light, a form of light undetectable by the human eye. While the colors that the eye can detect have wavelengths ranging from 400 to 750 nanometers, ...
Blue is from 400 - 500 nm (nanometers), green is from 500 - 600 nm and red is from 600-700 nm.
Radiated energy which forms that portion of the spectrum visible to the human eye, from 400 nanometers in the ultraviolet frontier to 700 in the infra-red boundary.

-White light spectrum is the electromagnetic wavelengths between 400-700 nanometers. Also referred to as the visible spectrum.
The wavelength of light is measure in units of nanometers (abbreviated as nm), and 1nm is a billionth of a meter (that's a US billion or 1000 million, not a UK billion which is a million million!).
Kodak Professional High Speed Infrared (HIE) film was a high-speed color slide film with moderately high contrast and was sensitive to light and radiant energy to 900 nanometers (nm) in wavelength. But it's gone now.

The particular arrangement of electrons in the atoms that make up the filter allows most frequencies of light to get through. But it hinders part of the UV range, which includes everything below 400 nanometers in wavelength [source: Chemistry ...
reduce lens flare by eliminating reflection off the surface of the glass; this has the effect of increasing contrast and giving images more "punch". Lens coating thicknesses are typically of the order of a few wavelengths of light, - a few nanometers ...
