One-Cuvette Sample Compartment
Overview of ChronosBH
ChronosBH is a time-domain (TCSCP) compact spectrometer for decay time measurements over a wide time scale, from picosecond to seconds. The instrument design features a T-format geometry for simultaneous acquisition on two emission channels. A variety of pulsed light sources can be coupled to ChronosBH including laser diodes, supercontinuum laser and multiphoton lasers. Detectors options include fast PMTs, hybrid PMTs and GaAs PMT. The instrument can be upgraded to steady-state fluorescence measurements using a xenon arc lamp.
The ChronosBH operations are fully automated; instrument control, data acquisition and processing are done through Vinci, the Multi-dimentional Spectroscopy software.
