Multi-axis Absolute Position Sensors

Mid-performance MAPS systems targeted at submicron characterisation and calibration of microscope stages, CNC, CMM, and similar tasks measuring XYZ and all rotational axes.

An enhanced MAPS series using high-resolution scales which yield deep sub-nanometre XY performance for nanotech industries and super-resolution microscopy among other applications.

The ultimate bespoke metrology tools. Multi-MAPS sensor configurations further enhance all 6DoF axes delivering uncompromising rotational accuracy and subatomic XYZ resolution.

Mistral M120-25-x-001

Anemos’ mid-performance MAPS™ Mistral systems measure one to a full six position dimensions, 6DoF, at one point in space/time with phenomenal precision using a tiny lightweight sensor.

MAPS revolutionises mechatronics with direct reporting of Abbe and other system error sources with unprecedented dynamic range and measurement envelope. Mistral optoelectronics includes an Anemos proprietary scale (a metrological reference or map), specialised sensor, and custom high-performance GPU platform for spatial computing at nanometre and microradian levels as a superior alternative to traditional interferometers, autocollimators, and single-axis encoders.

Key Features and Benefits
All-axis, 6DoF Provides a complete picture of linear and angular motion – no single axis can be precisely measured without all axis information.
High accuracy and superb resolution Obtain uniquely detailed system behaviour insights. Insensitive to atmospheric conditions, MAPS often beats performance of interferometers operating in air.
Absolute not incremental Enables reliable/repeatable (re)calibration over time – even after reassembly. Homing unnecessary, results immediately available.
Single point measurement Work-point readings decimate Abbe and other inter-axis anomalies.
Strobe illuminations Enables microsecond-level position capture for high-speed analysis (even at relatively slow sample rates).
Compact Integrates easily, retrofits to existing systems.
Ease of use Setup and go in minutes without finicky adjustments and zeroing.
Smart networked computing Software-defined function and Ethernet/WiFi networked results makes host application implementations extensible and readily upgradable.
Laser-free Obviates mirrors, retroreflectors, complex alignment tasks. No health and safety concerns. Robust, transportable.

Mistral Datasheet

1  Specifications are subject to change without notice and undergo continuous improvement. Enhancements and new features can be provided via software update.
2 Accuracy is defined as measurement within 1-sigma error limit over full travel envelope under 20.0°C constant-temperature conditions. Other potential thermally induced errors will depend principally on system implementation and scale material chosen.
3 Useful resolution is ultimately limited by low-level sensor noise (not the A/D resolution of conventional systems) and MAPS can achieve an unprecedented dynamic range of over 10 decades. Resolution, noise floor, and repeatability are generally equivalent or interchangeable, and do not degrade with XY measurement distance. Further improvement to these figures can be achieved through sample averaging.

MAPS Technology

MAPS™ is a patented, broadly scalable technology that is being applied across deep nanotech (where subatomic resolution has been demonstrated), through high-precision machining and microscopy, all the way to surveying applications and IoT remote monitoring.

System combinations   are available at value points covering diverse industries including metrology, machine tools, life sciences, nanotech, semiconductors, robotics, and more. This extraordinary new technology is performance proven through extensive in-house qualification and simulation, at customers, and through a series of validation experiments over several years at the National Physical Laboratory, UK.  Anemos packaged offerings are currently divided into three product line series.
