In this study an acousto- optic modulator had been implemented and investigated as a wave length tunable filter for halogen lamp in order to analyze its spectrum . This analysis had been performed with the aid of the He-Ne laser for alignment techniques of the halogen lamp .The wavelength of the lamp was (438-911) nm .
The experimental setup had been successfully able to analyze up to 1.4 nm resolution bandwidth of the halogen lamp spectrum .The results of this study confirm the ability of acousto -optic modulator to act as a tunable filter at a peak wavelength of 554 nm and bandwidth 100 nm
