Micromechanical mirror device, 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 (10, 20) are substantially arranged in a plane-parallel manner; wherein an intermediate space between the first and the second mirror element (10, 20) has a lower refractive index than the first and/or the second mirror element (10, 20); wherein the first and the second mirror element (10, 20) are locally arranged to be spaced apart from one another by at least one support structure; wherein the at least one support structure overlaps the first and the second mirror element (10, 20) in an axial direction, which is arranged perpendicular to the first and the second mirror element (10, 20); and wherein the at least one support structure comprises a material, or is formed from a material, which differs from a material from which the first and/or the second mirror element (10, 20) is formed; characterized in that the at least one support structure has at least one portion (232; 332; 432; 532) which protrudes from an outer surface (14, 24) of the first mirror element and/or of the second mirror element, wherein the outer surface (14, 24) 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 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 (10, 20) are substantially arranged in a plane-parallel manner; wherein an intermediate space between the first and the second mirror element (10, 20) has a lower refractive index than the first and/or the second mirror element (10, 20); wherein the first and the second mirror element (10, 20) are locally arranged to be spaced apart from one another by at least one support structure; wherein the at least one support structure overlaps the first and the second mirror element (10, 20) in an axial direction, which is arranged perpendicular to the first and the second mirror element (10, 20); and wherein the at least one support structure comprises a material, or is formed from a material, which differs from a material from which the first and/or the second mirror element (10, 20) is formed; characterized in that the at least one support structure has at least one portion (232; 332; 432; 532) which protrudes from an outer surface (14, 24) of the first mirror element and/or of the second mirror element, wherein the outer surface (14, 24) 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 respectively acting as a stop or as an anti-static-friction bump is formed from an electrically insulating material.
