Improved fluorimeter and detection method

A method and fluorimeter for flashing a target at several different levels for detection of fluorescence by a PMT without blinding the PMT at the highest level. Two lamps are provided each of which is powered to flash at two different levels that are staged in energy from the lowest of four to the h...

Zusammenfassung:	A method and fluorimeter for flashing a target at several different levels for detection of fluorescence by a PMT without blinding the PMT at the highest level. Two lamps are provided each of which is powered to flash at two different levels that are staged in energy from the lowest of four to the highest of four levels, and a shutter is provided to close off the PMT from exposure when an acceptable, detectable level of fluorescence is detected by the PMT.
