WebFor UV-VIS and NIR range spectroscopic applications, xenon is a popular light source choice, but most spectrometers use a halogen lamp. Xenon offers smooth emission for UV-VIS spectrums ranging from 750-1000 nm, but halogen lamps are more affordable. When a continuous UV spectrum is required, a deuterium arc lamp is the optimal light source. WebHR2 spectrometers provide reliable performance with rapid acquisition speed and excellent thermal stability for UV-Vis-NIR applications ranging from plasma monitoring to pharmaceuticals analysis.
