MAR1110.E | 2D Scanning Mirror



A MEMS (Micro Electro Mechanical System) mirror is a tiny solid-state scanning mirror (mirror on a chip) actuated by micro-size motors to move in one or two scanning directions. In order to create a laser-based display, a laser beam pointed at the mirror is precisely deflected and steered by the scanning mirror to reach a target point at a specific time.


  • 2D single mirror using a gimballed structure – it minimizes optical engine size and increases optical efficiency for 2-axis scanning

  • Combination of electrostatic actuator for the fast axis and electromagnetic actuator for the slow axis – improves robustness and optimizes performance for 2D scanning

  • Wide optical field of view (FOV), up to 45° (fast axis) & up to 30° (slow axis) – delivers large image and scanning area

  • Highly-sensitive, dynamic, 2D closed control feedback circuit – maintains stable peak performances even during changes in ambient conditions and manufacturing tolerances of the MEMS scanning mirrors

  • Mirror problem alarm signal both for the fast axis and the slow axis – supports eye safety operation of projection device

  • Compatible to a mirror controller with a standard digital video interface – simplifies system design and integration to other devices

  • Non-hermetic plastic package – reduces cost and maintains peak performances for MEMS scanning mirrors

  • Temperature Stability – gives a perfect image over a wide temperature range


MEMS Mirrors Flexibility and Customization


Maradin uses different packages for the 2D MEMS scanning mirrors that can be fully adapted to the needs of different systems and devices

FAQs MAR1110.E :

The MAR1110.E 2D MEMS scanning mirror is an improved version of the MAR1100.E 2D MEMS scanning mirror.  It has improved maximal stress design, better sensing signals and a more simplified manufacturing process

Yes.  The MAR1110.E 2D MEMS scanning mirror has different actuation methods for every scanning direction.  Electromagnetic actuation is used for the slow scanning axis and electrostatic actuation is used for the fast scanning axis.

We use capacitive sensing technology for both the fast and slow scanning axes.  For each scanning direction, a set of sensing comb-drives is carved into the silicon structure of the MEMS, providing an accurate sensing signal on the MEMS position.

Maradin has several MEMS mirrors controllers.  The MAR1110.E 2D MEMS scanning mirror can work with both the MAR2100 analog mirror controller and the MAR2200 digital mirror controller.
