Claim Text:
1. A MEMS device comprising, a mirror which is connected to a fixed portion by means of a first and second torsional arm, each of the first and second torsional arms are configured such that they can twist about torsional axes so as to oscillate the mirror about a first oscillation axis, and wherein the first and second torsional arms are each configured to have two or more meanders and wherein the first and second torsional arms are arranged symmetrically relative to the first oscillation axis, and wherein the cross sectional area of the first and second torsional arms is larger at each of the meanders compared to portions of the arms which are between successive meanders, and wherein the width of the first and second torsional arms increases from the portions of the arms which are between successive meanders to a maximum width at the apex of the meander.
