Abstract
The monochromator has, as a beam-diffracting element, a scanning mirror (3) which is fastened on a vibratory spring, preferably a spring-steel strap (8), clamped on one side. The vibratory spring is oscillated by way of an electromechanical self-energized oscillation circuit, a sensor (11a, 11b) which detects the deflection of the vibratory spring (8) is provided and whose output signal is used as a feedback signal for maintaining the oscillation of the vibratory spring (8). The amplitude of oscillation of the oscillating element can likewise be varied. With such a design it is possible to produce simply and inexpensively a monochromator with which a considerable spectral range can be swept and, in addition, the width and position of said spectral range can be variably adjusted.
