What is Ultraviolet?

Ultraviolet (UV) light is one form of electromagnetic energy produced naturally by the sun. Although invisible to the human eye, ultraviolet (UV) is part of the light spectrum that is shorter in wavelength than “visible” range. ISO-21348 defines UV in three wavelength ranges: UVA, UVB and UVC.

UV has many applications from optical sensing and measurement, which can be used to measure gases, impurities in substances, water “quality”, protein, DNA and much more. UV measurement techniques are very powerful tools, because the output is highly dependent on the wavelength used.

Using UV light to disinfect is a fast, effective and safe technique that utilizes UVC. When exposed to UVC light, microorganisms such as bacteria, viruses, cysts and mold are affected in a way such that they can no longer multiply, rendering them harmless. UV disinfection can be used on surfaces, in air and in water.

UV LEDs are the next wave in the LED revolution that brings the advantages of LEDs to the UVA, UVB and UVC regions of the spectrum. Miniature, robust, and operating with a low electrical power, UV LEDs can be manufactured with a highly stable output, operating at the optimum wavelength for the application, making them ideal for compact and portable solutions.
