ABSTRACT:
A scanning monochromator system which uses a directly coupled stepper motor to drive a spectral-dispersion element. The spectral-dispersion element is directly coupled to the output shaft of the motor. The movement of the motor is controlled with an electronic circuit that controls the motor winding current. The circuit includes a power driven section, a pulse-width modulator section and a computer section. The power driven section switches electrical current through the motor windings and can produce a variable pulse-width ranging from 0 to 100 percent modulation. The pulse-width modulator section accepts values from the computer section and converts these values into variable pulse-width signals for use by the power driver section. The computer section supplies values to the pulse-width modulator section based upon requirements for the motor movement and position. The required motor position is determined by the type of spectral-dispersion element and the desired wavelength selection of the monochromator.
