Abstract
An apparatus for time-gated fluorescence or luminescence detection includes gating means () arranged to alternately permit light from an excitation source () to be directed to a sample () along a first communication path (), and then permit light emitted from the sample to be directed to a detector () along a second communication path () while blocking the first communication path (): The gating means () may comprise a single chopper wheel or apertured disc, or a rotating or oscillating arm, and may further comprise one or more reflective facets (). The gating means () may be driven via a magnetic rotor, with a ferrite bead placed to offset rotor magnets with respect to drive coils, when at rest, so as to assist with self starting.
