Nova’s analyzers leverage optical spectrophotometry, a quantitative analysis technique using light to directly measure component concentrations in a plating solution. The highly accurate and fast method combines spectrometry, the measurement of the spectrum, and photometry, the measurement of light absorption at one or several wavelengths. Requiring little maintenance, optical spectrophotometry covers multiple parts of the electromagnetic spectrum, such as UV (ultraviolet) wavelengths of 200nm-400nm and VIS (visible light) wavelengths of 400nm-800nm respectively.
