Ultraviolet radiation ranges in wavelength from 10 nm to 400 nm, and can be divided in various ways, with the three most common ranges being UVA (315-400 nm), UVB (280-315 nm) and UVC (100-280 nm). Its ionization properties can cause various substances to glow or fluoresce when in the presence of UV light. The sun is the most commonly known source that contains ultraviolet radiation.
UV light has a number of beneficial applications, such as water purification, that requires monitoring the amount of radiation emitted with the use of a photo sensor to ensure minimum power requirements are met throughout the lifetime of the lamp. It can also be used to treat skin conditions and generates the production of vitamin D within the human body.
Excelitas offers various detectors that can detect UV light, from common PN photodiodes to more high-performance sensors in cases where the amount of radiation is very minimal.
Excelitas is a leading supplier of optoelectronic sensors and modules that covers the entire electromagnetic spectrum, from Gamma rays all the way to the Far Infrared. Whether you are looking at visible photons for fluorescence measurements, long-wavelength infrared for motion sensing, gamma rays for nuclear medicine, or anything in-between, chances are we have the detector you are looking for.
Did You Know?
Some animals, including birds, reptiles, and insects such as bees, can see UV light. Many fruits, flowers, and seeds stand out more strongly from the background in ultraviolet wavelengths as compared to light that is visible by humans.
