Results of an investigation of acousto-optic (AO) cells using single crystals of magnesium fluoride ( MgF 2 ) are presented. Two acousto-optic tunable filter (AOTF) cells for imaging application have been designed and tested in the visible and ultraviolet (UV) regions of the spectrum from 190 to 490 nm . The two imaging filters were developed by using the wide-angle AO interaction geometry in the ( 010 ) and ( 1 1 ̄ 0 ) planes of the crystal. These filters were used to obtain spectral images at the shortest wavelengths achieved so far. Advantages and drawbacks of this crystal are discussed and photoelastic, acoustic, and AO properties of MgF 2 are examined. The investigation confirmed that MgF 2 -based AOTF cells can be used in the deep UV region up to 110 nm .
