MEMS SCANNING MICROMIRROR

摘要

A MEMS-micro-mirror (30) is provided comprising a mirror body (50) that is rotatably arranged in a mirror frame (60) around a rotation axis (58) extending in a plane defined by the mirror body. The rotation axis extends through a first and a second mutually opposite end-portion (51, 53) of the mirror body. The mirror has a reflective first main surface (55) and opposite said first main surface a second main surface (57) provided with a first and a second pair of reinforcement beams. The pair of reinforcement beams (91a, 91b) extends from the first end-portion (51) in mutually opposite directions away from the rotation axis. The second pair of reinforcement beams (93a, 93b) extends from the second end-portion (53) in mutually opposite directions away from the rotation axis. Reinforcement beams of said first pair extend towards respective ones of said second pair.
