Nano Positioning Components and Platforms
Invenios is
a manufacturer of precision linear and rotary stages, piezo flexures,
anthropomorphic platforms and PC-based control components; serving
systems integrators who need robust components that can be deployed
quickly in a broad range of traditional and emerging micromanufacturing
applications. Unlike other nanopositioning component suppliers, Invenios
components achieve high static and dynamic stiffness enabling them
to not only align, but also to hold alignment during component
bonding and attach operations. Our positioning components eliminate
secondary bend-align steps and other rework.
The result is higher alignment precision, higher assembly throughput
and elimination of the all-too-common rework steps required by less
robust nanopositioning solutions. For instance, Invenios nanopositioners
can hold alignment to within 50 nm during laser welding-based fiber
attach processes for laser diode assembly. To see a graph illustrating
the dynamic response of our InvenioFlex nanopositioner in a

Systems integrators that embed Invenios nanopositioning components
into their production cells reduce or eliminate the "tweaking" of
hardware and software necessary to achieve assembly throughput, thus
increasing the speed of deployment of their high-performance precision
assembly solutions.

Products
Precision Linear and Rotary Stages
 Invenios'
scalable precision ball-screw stages meet demanding nanopositioning
requirements in applications employing short to medium travel. The
Nano series employs patented bearing technology that achieves sub-micron
out-of-plane motion—only .05 µm over 10 mm—required
in the most demanding applications and a dual-loop feedback option
to achieve precision linear resolution and repeatability of 1 nm.

 The
Reference series employs tighter tolerances (<10nm over 10mm
straightness) on the ball-screw and bearing components to serve
as the prime mover in such demanding applications as atomic force
microscopes, nanoscale machining, and nanoscale printing applications.
Invenios stages can be assembled into more complex rectilinear motion
applications without need of interposing mounting plates, thus increasing
the available acceleration for nano-robotic applications. More information

Anthropomorphic Assembly Platforms
 The
InvenioSix assembly platform delivers long range translation
(±15 mm) and rotation (± 15°) designed to meet
the most demanding 6 Degree-of-Freedom alignment and assembly applications.
Unlike most anthropomorphic nanopositioners that use sliding bearing
elements to couple motions to the platform output, the InvenioSix
employs a tripod structure that couples the motions from x-y nanopositioners
(see above) at the base of each leg to the platform output with
proprietary rotary flexures that provide direct coupling without
backlash and other sources of "lost" motion. The result is high
static and dynamic stiffness on the nanoscale that makes the InvenioSix
the ideal choice in high force applications including tri-color
optical alignment in light engines and high-performance color imaging
systems. The InvenioSix has mounting surfaces on two planes and
can be mounted up-right, upside-down, and on its side.
Reference stages achieve a flatness of motion of 10nm over 10 mm,
meeting the needs of atomic microscopes and positioning systems
that require extended range of motion with tight out-of-plane error
tolerances. Invenios also manufactures a series of dual-axis, piezo-driven
flexures achieves extended range of motion-scalable from 50 to 500
with 16 bit dynamic range in an industrially-hardened package. More
