Photonics instrument development teams are facing increasing pressures to commercialize faster with fewer staff. Accelerated timelines require teams to focus on their core competency and look for outside solutions for non-core technologies. Embedded positioning modules provide a fast and efficient solution for integrating micro positioning capabilities in less time, reduced system size, enhanced features, and lower total cost.
Embedded rotary or linear positioning modules are also called all-in-one systems and combine actuator, sensor, precision guide mechanism, drive and control electronics, closed-loop firmware, and digital IO. Compared to standard components from catalog suppliers, connectors, and cables to separate electronic boxes are eliminated.
Embedded positioning is enabled by several innovations including:
- Improved motor efficiency, smaller size, and reduced voltage.
- Small, precise, and low power sensors with built-in interpolation electronics.
- Modular precision bearings.
- Advanced integrated circuits for efficient driver chips and powerful microprocessors.
Embedded positioning solutions compliment parallel photonics innovations in detectors, sources, processing power, imaging, biology, quantum devices, and micro-optics. All-in-one positioning enables more closely packed light and sample channels to increase throughput. Active control of focus, beam quality, and spot location are achieved in increasing smaller photonics instruments.
Additional benefits include improved signal-to-noise, reduced sample sizes, reduced power and heat, and robust operation over a wider range of environments. Commercial examples of embedded motion include brushless DC, stepper, and piezoelectric motors. A comparison of these examples is provided. A method for selecting the best embedded motion module for a particular instrument application is presented based on several criteria including size, power, speed, stroke, and precision.
