DESCRIPTION
The TALP1000B is a high-performance micromirror designed for use in multiple light steering applications. The
large 2-axis micromirror is constructed of single crystal silicon, which has no grain boundaries and is virtually
defect free. This produces a hinge with no work hardening and gives the TALP1000B superior reliability
characteristics. The gold coated optically active surface of the TALP1000B provides excellent reflectivity in the
700 nm –10 um wavelength range. The mirror’s large size, large radius of curvature and high reflectivity make it
easy to incorporate into many optical designs.
The electromagnetic drive of the TALP1000B allows low voltage and low-power actuation. The mirror can be
driven using an analog drive resulting in precise pointing resolution over the entire range of motion. Each rotation
axis of the device is individually and independently actuated.
Integrated position feedback on the TALP1000B is optical based and provides greater than 13 bit pointing
precision. Additionally, the position feedback can be used in conjunction with a servo loop to achieve <5
millisecond point-to-point switch times.
The ceramic circuit board base provides a mechanically rigid design, and the three point mounting interface
allows precise and repeatable assembly into system hardware. The compact size of the TALP1000B is ideal for
systems with small footprint requirements.
