The S13989-01H is an electromagnetically driven MEMS mirror produced by applying Hamamatsu unique MEMS*1 technology. Two-axis operation (X-axis and Y-axis operation) enables two-dimensional scanning (raster scanning)*2 using reflections of laser light or the like.
Typically, electromagnetic mirrors have a configuration in which magnets are placed around the mirror chip. However, our MEMS mirrors have powerful compact magnets placed under the mirror chip. Even though they are compact, they achieve a wide optical deflection angle (fast axis: ±20°, slow axis: ±12°).
They also feature high reliability with a hermetically sealed package, low voltage drive, and linear operation*3 that allows the optical deflection angle to be set arbitrarily.
They can be applied to various scanning mechanisms for obtaining 2D or 3D information. Some applications include shape recognition using machine vision, laser ranging, obstacle detection for automated guided vehicles and the like, and laser scanning microscopes.
*1: Micro-Electro-Mechanical Systems
*2: A scanning method that composes a two-dimensional image. First, a line is obtained by one-dimensional scanning, and then the line is scanned in the perpendicular direction to compose an image.
*3: Slow axis
1) Machine vision
2) Laser ranging
3) Laser microscope
In addition to MEMS mirrors for one-dimensional scanning, mirrors for two-dimensional scanning have been added to the lineup. Select the appropriate product for your application.
