MAR1100 – MEMS 2D LASER SCANNING MIRROR

A 2D MIRROR WITH BOTH ELECTROSTATIC AND ELECTROMAGNETIC ACTUATION METHODS

A MEMS (Micro Electro Mechanical System) mirror is a tiny solid-state mirror (mirror on a chip) actuated by micro-size motors in one or two dimensions. 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.
Maradin's technology suite is the core of Maradin MEMS scanning mirrors.

MARADIN'S TECHNOLOGY INCLUDES THE FOLLOWING KEY ELEMENTS:
  • Fast electrostatic (ES) actuator with minimal power consumption. The ES actuator operates in the self-resonance frequency of the mirror and is ideal for high scan frequencies (tens of KHz).

  • Strong and accurate electromagnetic (EM) actuator. The EM actuator is ideal for point-to-point or slow scan patterns.

  • Capacitive sensors measure the mirror angular position with very high precision and fast response.

  • Sophisticated control circuitry and algorithms perform continuous, close control of the mirror motion, ensuring the utmost accuracy, repeatability and temperature stability.

KEY FEATURES AND BENEFITS
  • 2D single mirror– Minimizes optical engine size and increases optical efficiency

  • Combination of electrostatic (H) and electromagnetic (V) actuators – Improves robustness and optimizes performance

  • Wide optical FOV, 45° (H) x 30° (V) – Delivers large image/scan area

  • High-sensitivity, dynamic closed control loops – Maintain stable peak performance even during changes in ambient conditions

  • Static mirror alarm signal – Supports eye safety

  • MEMS controller with standard digital video interface – Simplifies system design and integration

  • Non-hermetic plastic package – Reduces cost

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