- Model UVEGA - Emission Monitoring System



The heart of the UVEGA system is based on charge capacitor diode array (CCD) technology. The fundamentals of the system’s operation is simple. First, ultra-violet light is generated from some type of source, usually either a deuterium or xenon lamp. The light is collected and concentrated using special optics. The concentrated light then passes through an input lens into the spectrometer via a fiber optic coupling. Once inside the spectrometer, the light is broken out into it various wavelengths by sending it through a holographic grating. The light then hits the CCD array which in turn charges the capacitor. The capacitors are discharged at a sample rate set by the user and the light signal at each light frequency is proportional to the total charge of each capacitor. Finally, a graphical representation of the UV spectra is produced by measuring the electrical charge of each capacitor at each given wavelength (signal intensity vs. wavelength).
