By Jim Raymont, Joe May, Mark Lawrence and Paul Mills, EIT Instrument Markets The Fundamental Paradox of Measurement Measurement is important to set process parameters and to identify if the process is running within those parameters. When things change in the process, measurement provides valuable clues that help locate the source of the problem(s). Without measurement, we … [Read more...] about Total Measured Optic Response: A New Approach to UV LED Measurement

Understanding Ultraviolet LED Wavelength
By Mike Higgins, east regional sales manager, Phoseon What is ultraviolet wavelength? The sun is a source of the full spectrum of ultraviolet radiation, which is commonly subdivided into UV-A, UV-B and UV-C. Wavelength, a fundamental descriptor of electromagnetic energy, is the distance between corresponding points of a propagated wave. Typical UV light source emission … [Read more...] about Understanding Ultraviolet LED Wavelength
