The new Delta series of fluorescence TCSPC lifetime systems are the fastest, most flexible, and most affordable lifetime solutions available. The Delta series includes the DeltaPro, the very affordable and simple to use filter-based lifetime system with performance that rivals most high end systems. For the ultimate flexibility and upgradability, DeltaFlex, our modular system, seamlessly integrates monochromators, polarizers, the widest array of sources (LEDs, laser diodes, supercontinuum lasers) and detectors (including NIR). This enables lifetimes from 25 ps to 1 sec, over wavelengths spanning the UV to NIR, to be measured. The culmination of over 40 years of lifetime experience, Delta series highlights include: the fastest sources (up to 100 MHz), the widest lifetime ranges (ps to sec), virtually unlimited configurability with our new F-Link plug-and-play architecture and advanced lifetime analysis software. The Delta series is truly the next generation of fluorescence lifetime systems.
