Tuneable VUV Light Source

Product Description

Excitation from 110 nm upwards is possible with a CW Deuterium Source and a specially designed nanosecond flashlamp (filled with hydrogen or dueterium) can be used for TCSPC lifetime measurements. The optical path from the excitation monochromator to the sample is also evacuated using a special light guide. The area around the sample is floowed with flowing nitrogen gas to reduce atmospheric absorption of the VUV radiation. The tuneable VUV source is availabe for the FLS980.
