DeltaTime

Overview

The DeltaTime TCSPC lifetime plug-in offers acquisition speed, flexibility, and affordability unavailable in any other hybrid fluorescence solution available. DeltaTime seamlessly integrates monochromators, polarizers, and other accessories with the widest array of sources (LEDs, laser diodes, supercontinuum lasers) and detectors (including NIR), providing lifetime coverage from 25ps to 1sec over wavelengths spanning the UV to NIR.

The culmination of over 40 years of lifetime experience, DeltaTime highlights include: the fastest sources (up to 100 MHz), the widest lifetime ranges (ps to sec), virtually unlimited configurability and advanced lifetime analysis software. DeltaTime is part of our Delta series...truly the next generation of fluorescence lifetime systems.

Features

  • Fast…lifetime acquisition times from one millisecond
  • Sensitive…uses single-photon counting detection
  • Accurate…crystal locked timing circuits never require recalibration
  • Wide range…resolves lifetimes from 25ps to 1 second
  • Modular…easily reconfigured as measurement requirements evolve
  • Compact…desktop dimensions
  • Convenient…single USB 2.0 connection to PC
