Abstract
Electrical control of the excitation and emission wavelengths of a luminescence spectrometer may be conveniently obtained by coupling the grating drive shafts directly to limited-rotation torque motors. The relationship between the wavelength and the applied voltage is very nearly linear, and the reproducability is ±1 nm or better. The torque motors are driven by operational amplifier circuits which provide convenient and wide-range control of scan parameters. Stereo-fluorograms may be recorded automatically on an X-Y recorder.Keywords
