Abstract

A simple method is described for extending the spectral region of the Farrand spectrofluorometer Mark I. The wavelength adapter is inexpensive and can be inserted rapidly. A Hamamatsu R-446 photomultiplier tube (PMT) in conjunction with the wavelength adapter extends the spectral region to 900 nm. The fluorescence and phosphorescence spectra of Victoria Blue B in ethanol were obtained in this extended region.
