Powerful light sources are a must when conducting UV-Vis absorbance spectroscopy. Ocean Optics’ new 75-watt, short-arc HPX-2000-HP-DUV Xenon Light Source is suitable for applications requiring high-intensity lamps. It provides continuous spectral output from 185 to 2,000 nm and has up to 2,000 hours of bulb life. The integrated shutter can be controlled via a switch or triggered by a TTL signal so taking measurements and making adjustments does not affect stability. Optimum warm time is 40 to 60 minutes.
