MAR2100 | Mirror Controller IC

MAR2100 MIRROR CONTROLLER IC

The MAR2100 is a Driver and control IC for Maradin’s MAR1110.E dual-axis MEMS-based scanning mirror. MAR2100 is targeted for miniature laser-based displays and sensors.

MAR2100 drives and controls Maradin’s MAR1110.E dual-axis scanning mirror and generates the timing signals to synchronize the laser module through the Host, also called a Data Manipulator. As the MAR1110.E scanner has two uncoupled actuators – one for horizontal scan and one for vertical scan, MAR2100 controller IC supports both drivers.
