The 2D devices are operated in open loop and are currently available with a mirror has a reflective surface of 2.5x3.6mm. It's best suited in applications where small size and low power consumption are important.
The 2-D mirror has a large reflective surface of 16x11mm. Using magnetic actuation, the deflection angle is set linearly with the driving current. As an option, the device could include an internal optical feedback sensor for closed loop actuation.
To avoid an optical feedback loop, the micro mirror is designed to minimize effects such as drift, hysteresis and temperature dependent performance. The angle is set using electrostatic actuation.
Electrostatic driven mirrors combine the high pointing stability and the high fill factor required typically in fiber optic components.
Since 1999 Sercalo is a leading supplier for optical MEMS components. Sercalo's skills span the entire process of manufacture, from the design of the MEMS chip to its fabrication and assembly.
