What is Ultraviolet Technology 

When sunlight passes through a prism, it separates into the colors we see in a rainbow.  Each separate color has its own wavelength.  Everyone and every living thing enjoys the benefits of sunlight.  Without it, the earth would be a cold, lifeless planet.  Ultraviolet light, although it is invisible to people also separates into different wavelengths.  There are certain, specific wavelengths that can be used indoors for a number of purposes. 

There are four principal wavelengths in the ultraviolet spectrum that lend themselves to specific applications.  Photochemical UV-A, Erythemal UV-B, Germicidal UV-C, and extreme shortwave UV Energy, which generates ozone. 

UV-A is responsible for the familiar suntan.  It is a normal component of sunlight, that by virtue of its relatively longer wavelength can penetrate the atmosphere.  Applications have included inspection of fluorescent surfaces, tanning beds and treatment of shin diseases. 

UV-B is found in the middle wavelength region of the ultraviolet spectrum.  Principle uses have been medically for the treatment of skin diseases and for testing purposes in the aging/degradation cycles of products.

UV-C is shortwave ultraviolet radiation. Primary uses have been for the destruction of bacteria and other microorganisms in air, liquids, or on surfaces.

The destruction of germs and bacteria by germicidal ultraviolet light is accomplished quickly and effectively. The UV-C rays strike the various microorganisms whether they are bacteria, virus, yeast, mold or algae and they break through the outer membrane. The radiation reaches the heart of the organisms (commonly known as the DNA) where it causes abrupt modifications. The modified DNA transmits incorrect codes or messages and this impairment actually brings about destruction of the microorganisms. 

UV-C is the wavelength used in germicidal applications.  It is well known that ultraviolet germicidal lamps can destroy any microorganism that comes in contact with its powerful UV-C rays.  Its total effectiveness is based on time and intensity. This method is recommended by the Centers for Disease Control for its germicidal effects.
