The radiation source is a xenon flash-lamp. The 3
continuous spectrum of light from 200 nm to 900 nm. The light output

sensitivity requirements. You can economize during automatic operation using
keyboard setpoints, so the lamp flashes during your analysis only. The lamp
can be used until it no longer ignites, but the noise level may increase with
usage.
UV degradation, especially below 250 nm is significantly higher compared to
Visible wavelength range. Generally the "LAMP ON during run" - setting or
using "economy mode" will increase lamp life by a magnitude.
