Uv C Light

One of the three types of invisible light rays together with ultraviolet a and ultraviolet b given off by the sun.

Uv c light. Uv c is found within 100 280 nm range. Uv c light uv cleaner bag portable usb input jumbo size capacity 5 15 30 minutes timer uvc without ozone smell sterile tote ctuv t2 4 5 out of 5 stars 65 89 76 89. Although ultraviolet c is the most dangerous type of ultraviolet light in terms of its potential to harm life on earth it cannot penetrate earth s protective ozone layer. Fortunately almost all uv c rays are blocked by the atmosphere and typically do not reach the earth s surface.

Ultra violet uv light is invisible to the human eye and is divided into uv a uv b and uv c. We do understand that there are certain benefits to using uv c light in various applications. Ultraviolet light in the c spectrum uv c is energy rich light with a wavelength of 10 nanometers nm up to over 400 nm. Uvc refers to ultraviolet light with wavelengths between 200 280 nanometers nm.

Ultraviolet germicidal irradiation uvgi is a disinfection method that uses short wavelength ultraviolet ultraviolet c or uv c light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their dna leaving them unable to perform vital cellular functions. Uv c light which has the most energy of all three types is the most harmful but it fortunately doesn t reach the earth s surface because our atmosphere absorbs it. Given the brightness from uv c lamps that 3 4 of visible light gives one an idea of the amount of uvc energy a lamp produces. Ultraviolet uv is a form of electromagnetic radiation with wavelength from 10 nm with a corresponding frequency of approximately 30 phz to 400 nm 750 thz shorter than that of visible light but longer than x rays uv radiation is present in sunlight and constitutes about 10 of the total electromagnetic radiation output from the sun it is also produced by electric arcs and specialized.

Light in the uvc wavelength can be used for disinfecting water sterilizing surfaces and destroying harmful micro organisms in food products and in air. Uvgi is used in a variety of applications such as food air and water purification. The remainder is visible light blue hue and a small amount of infrared heat. In the graph can be seen that germicidal action is maximized at 265 nm with reductions on either side.

However this is a good thing as uv c light can be harmful to many organisms if they experience periods of time with prolonged exposure.
