About us

Direct Optics Inc., was founded with a commitment to advancing air measurement. Through years of research and recognizing the need for a more accurate and efficient way to measure NO2 and NOX, we developed the G60 – the first dual-channel CRDS analyzer capable of direct measurement, eliminating the inaccuracies of traditional conversion techniques. Built on our expertise in Cavity Ring-Down Spectroscopy (CRDS), the G60 ensures reliable regulatory compliance and supports atmospheric research. This breakthrough provides continuous, real-time data for both regulatory and research applications.
