Time-Domain Lifetime Measurements on ChronosBH™

Introduction

ChronosBH is the first of a new ISS product line of time-domain fluorimeters. ChronosBH combines proven ISS technology and Becker & Hickl components for precise TCSPC measurements using laser diodes, Ti-Sapphire, white and other pulsed lasers as light sources. It features parallel beam geometry and can be upgraded to perform steady state and time-resolved measurements. ChronosBH is fully automated using Vinci – Multidimensional Fluorescence Spectroscopy, a Windows-based software that enables complete remote instrument control and data analysis.

To demonstrate the capabilities of ChronosBH we have measured several fluorescent standards using a pulsed 447-nm laser diode light source. For additional information about ChronosBH we refer you to our website.
