LifeSpec 1400 - Data
Acquisition
TCSPC offer the highest dynamic range and temporal resolution
available. For TCSPC data acquisition we incorporate our PC
plug-in card the TCC900 into our spectrometers. This computer
controlled card with PCI interface, incorporates all the
necessary electronic modules required for Time Correlated
Single Photon Counting. This includes constant fraction
discriminator, variable nanosecond delays, time to amplitude
converter and large memory for multi-channel analysis. All
that is required to perform TCSPC measurements is an optical
trigger pulse from the excitation light source and the raw
detector output from a single photon counting detector
connected to the START and STOP inputs of the TCC900
respectively.
All the important operating parameters of the TCC900 are fully
computer controlled. This includes discriminator thresholds,
zero crossing levels, frequency dividers, shifting delays and
time offsets, time range and number of data channels, switch
between forward and reverse mode, stop conditions.
The TCC card features:
• PCI interface
• Time ranges 2.5ns to 50microseconds full scale
• Time resolution from 610fs/ch
• Ultra-low jitter <25ps
• Forward and Reverse modes
• Exceptional differential non-linearity
• Integrated shifting delays
