At the upcoming Photonics West exhibition January 31st to February 2nd in San Francisco, leading nanometer-precision motion control innovator ALIO Industries will be showcasing its capabilities for exacting photonic and optical fiber alignment applications on booth 4842.
A glance at any industry vertical will show the increased use of LEDs and laser, optical glass, detectors and image sensors, lenses, prisms, optical filters, gratings, and optical fibers. There is also a growing demand for the adoption of silicon photonic chips using light signals rather than electricity.
In the production of systems based on photonic chips, accurate and repeatable optical fiber aligment and fixation are key. Indeed for any precision devices using optical components associated manufacturing processes — which may include the alignment and attachment of free-space optics, the attachment of pigtails, fiber arrays, and waveguides coupled to various types of light source, and the assembly and testing of hybrid opto-electronic devices and high-power laser diodes — represent cutting-edge, high-precision production systems that utilize advanced automation approaches.
Bill Hennesey, President of ALIO Industries says, “For applications such as the alignment of optical fibers or optical devices it is vitally important that motion is controlled in tip and tilt as well as in X, Y, and Z axes. Modular system architectures are required, so that exploratory, proof-of-process development — as well as high-volume manufacturing requirements and anything in-between — are addressable. ALIO’s hybrid planar and point-precision motion system design is two orders of magnitude more precise than any competitive solution. They are perfect for the accurate, repeatable, and reliable positioning of tiny components over millions of cycles if one of the main considerations is the fast positioning of multi-axis systems with advanced functionalities like multiple tool center points/center points of rotation, maximized usable space, and fast active alignment. In addition, our Hybrid Hexapod® combining a precision monolithic XY stage, tripod, and continuous rotation theta-Z axis and boasting less than 100 nm 3-dimensional 6-axis point precision repeatability is a game changer when considering mission critical positioning applications.”
ALIO Industries is unique in being able to provide nanometer-precise motion control systems for optical fiber alignment which requires positioning on 6 axes. Most alternative hexapod solutions on the market can only achieve micron-level precision repeatably, but the unique design of ALIO’s Hybrid Hexapod® exhibits much higher performance and renders traditional hexapod kinematics obsolete, with orders-of-magnitude improvements in precision, path performance, speed, stiffness and a larger work envelope with virtually unlimited XY travel, and fully programmable tool-center point locations. Its nanometer-level precision makes the Hybrid Hexapod an essential technology for mission critical photonic applications.
Hennessey continues, “For manufacturers working on ultra-precise photonics applications, ALIO’s nanometer-precise hybrid planar and Hybrid Hexapod® motion control solutions are true enabling technologies. The Hybrid Hexapod®, for example, due to the use of high-dynamic non-contact linear motors, can achieve velocities from microns per second to hundreds of millimetres per second; 1-2 orders of magnitude better bi-directional repeatability when compared with conventional hexapods; nanometer level step sizes; no backlash; no hysteresis; smoother, straighter, flatter motion; and a mean time between failures of over 80,000 hours! The Hybrid Hexapod® technology allows for the provision of documented proof of performance over all 6DOF of a body in motion at the nanometer level of precision. As such it is unique, and explains why ALIO is now working with leading blue-chip OEMs in the photonics sector which are innovating and achieving successes previously unattainable.” Come and visit the ALIO team at Photonics West and see how we can tailor motion control solutions to match your exacting applications.
In general — and indeed perhaps exacerbated by the disruption caused by the recent pandemic — manufacturers need automated processes to boost productivity and speed products to market in order to remain competitive. Production machinery also needs to be ultra-reliable and operate at the required capacity. At the heart of such automated processes is reliable and repeatable motion control which is critical for keeping production lines operating optimally, and in turn reducing lost time due to manual intervention.
ALIO Industries has been at the vanguard of innovation in nanometer-level precision motion control solutions for over 20 years, and is a specialist in the area of development of motion control systems for industrial automation and manufacturing. The company advocates that designers when specifying motion control for their specific applications, do not feel forced to choose the least expensive solution for the application as it exists today, but choose a system that operates optimally as application requirements change and evolve over time.
Peter Lehner, Sales & Marketing Director at ALIO says, “When specifying a motion control solution for exacting industrial manufacturing applications, beyond an analysis of the specific functionality of a particular system, it is also of vital importance to analyse how an application is likely to develop in the medium to long-term (i.e what new functionality or sub-systems will be required over time) and, for example, what space constraints that may dictate system architecture and component choice. A snap decision when specifying a motion control solution may be costly later in the product development process. There are some common mistakes. First, and most common, a motion control solution is specified without enough focus on the end application. Often, the motion control system is selected first, either from a supplier that is familiar, or one that seems to have all the latest bells and whistles. Choosing the motion control system first can lead to the use of components not ideal for the end application, and workarounds to get a system to work correctly which increases development time and costs. Also, without an eye on the future, a hastily chosen motion control system will limit new functionality, and while choosing the least expensive solution may seem prudent in the short term, in the medium to long-term it can severely impact ROI.”
ALIO Industries has developed a sophisticated product configurator on its website to allow customers to put in headline application requirements, and be presented with viable motion control solutions which cover present and future application requirements. The product configurator allows ALIO customers the ability to specify the basic motion control requirements that are available in the standard ALIO portfolio, and to apply ALIO’s support and experience to optimize the motion control recipe ensuring a perfect application specific fit. So if users know the direction of motion required; the basic product type (i.e. linear motion, z-lift vertical stages etc.); application specific needs (i.e. smooth continuous movement, step and settle etc.); open center or closed; travel range; maximum weight of payload; level of bi-directional repeatability; and the environment the application is to be used in (ambient, cleanroom, or vacuum); the product configurator will display ALIO’s relevant options.
Lehner concludes, “Our product configurator (coupled with our unrivalled expertise in the area of nanometer-level precision motion control), means that we fully understand that achieving competitive advantage in exacting specialized industrial manufacturing scenarios requires the use of the right motion control tools. Take a look at the production of top-notch motors using electromagnetic components. In such a scenario, an efficient coil with a high fill factor minimizes not only the amount of material and volume required for a given linear motor, wound electromagnetic component, or sub-component, but simultaneously improves the heat conductivity of the winding. Instant in-process, sub-micron corrections of the product during manufacture (such as during the winding process for an electromagnetic motor) help to optimize components and drive innovation. In ultra-high-end industries like this, it is vital to use the best quality motion control products available, and to have available highly-customizable products and processes. ALIO’s precision linear X, linear Z and rotary stages enable specialized manufacturing as a fully integrated, value-adding feature that utilizes advanced systems at a competitive cost point allowing practical customization and an overall increase in product quality.”
