The Lifespec II is a compact, fully integrated, high performance, spectrometer designed for use with high repetition rate pulsed femtosecond and picosecond lasers. The system is a fully automated solution, combining hardware and software in a single package for fundamental research and routine laboratory applications. Its zero temporal dispersion optics, using double-monochromators in subtractive mode, sets the standard for technical performance in measuring ultra-fast decays.
This is the only turn-key fluorescence lifetime measurement system on the market featuring a subtractive double-monochromator, which provides for zero temporal dispersion and allows the instrument to measure fluorescence lifetimes down to 5 ps with ultrafast lasers.
