Modernization of the atomic-absorption spectrometer with a controlled acoustopic lightfilter

Abstract

The method of modernization radiation source atomic-absorption spectrometer by using controlled acousto-optic filter and lamp with continuous spectrum was considered in this work. The wavelength of light can be controlled by changing the frequency of the ultrasonic wave. The frequency is fed to the exciter acousto-optical cell. Advantages and disadvantages of a managed source and advantages of using this method were considered.
