Micromechanical mirror device (200-600), comprising: a first mirror element designed to be planar; and a second mirror element designed to be planar; wherein the first and the second mirror element are substantially arranged in a plane-parallel manner; wherein an intermediate space between the first and the second mirror element has a lower refractive index than the first and/or the second mirror element ; wherein the first and the second mirror element are locally arranged to be spaced apart from one another by at least one support structure (230-630); wherein the at least one support structure (230-630) overlaps the first and the second mirror element in an axial direction (A), which is arranged perpendicular to the first and the second mirror element ; and wherein the at least one support structure (230-630) comprises a material, or is formed from a material, which differs from a material from which the first and/or the second mirror element is formed; characterized in that the at least one support structure (230-630) has at least one portion (232; 332; 432; 532) which protrudes from an outer surface of the first mirror element and/or of the second mirror element , wherein the outer surface of the first mirror element and/or of the second mirror element is in each case remote from the intermediate space between the first mirror element and the second mirror element , and wherein at least the at least one portion (232; 332; 432; 532) of the at least one support structure (230-630) respectively acting as a stop or as an anti-static-friction bump is formed from an electrically insulating material. a first mirror element designed to be planar; and a second mirror element designed to be planar; wherein the first and the second mirror element are substantially arranged in a plane-parallel manner; wherein an intermediate space between the first and the second mirror element has a lower refractive index than the first and/or the second mirror element ; wherein the first and the second mirror element are locally arranged to be spaced apart from one another by at least one support structure (230-630); wherein the at least one support structure (230-630) overlaps the first and the second mirror element in an axial direction (A), which is arranged perpendicular to the first and the second mirror element ; and wherein the at least one support structure (230-630) comprises a material, or is formed from a material, which differs from a material from which the first and/or the second mirror element is formed; characterized in that the at least one support structure (230-630) has at least one portion (232; 332; 432; 532) which protrudes from an outer surface of the first mirror element and/or of the second mirror element , wherein the outer surface of the first mirror element and/or of the second mirror element is in each case remote from the intermediate space between the first mirror element and the second mirror element , and wherein at least the at least one portion (232; 332; 432; 532) of the at least one support structure (230-630) respectively acting as a stop or as an anti-static-friction bump is formed from an electrically insulating material. <EOS>
