With an Olis® Hummingbird double monochromator outputting a homogeneous excitation beam of arbitrary bandwidth, one has high resolution, low stray light excitation. With a single grating monochromator on the excitation side, one obtains the maximum emission signal.

Our 150-watt xenon arc lamp in a specialized elliptical mirrored housing outputs the intensity of a typical 450-watt xenon arc. A high sensitivity photon counter or a high-speed photomultiplier tube is used for detection. Arbitrary amounts of signal averaging are possible with both detectors. The photon counter, with higher sensitivity, responds in 10 milliseconds to 2.5 second intervals; the photomultiplier tube provides for an uninterrupted stream of acquisition, the rate of which is limited only by the 20 MHz A/D card or user-supplied digital oscilloscope and available memory.

Spectral ranges captured by the detectors is 210-650 nm or 300-850 nm with the photon counter, approximately 200-800 nm with the photomultiplier tube, and to 2600 nm with available InGaAs detectors.
