COMPACT MULTIWAVELENGTH PHASE FLUOROMETER

摘要

The present instrument is a compact instrument capable of operating as a steady-state fluorometer or as a phase fluorometer, and thus it is able to measure steady state fluorescence intensity and fluorescence lifetime from a flourescent sample. The light source provides four user-selectable excitation wavelengths generated by light-emitting diodes (LEDs), and has an autocalibration feature and a means to compensate for phase measurement errors due to phase-amplitude crosstalk in the detection electronics.
