CONTROL AND GUIDANCE FibreMaxHP alignment platform
Aerotech has released the FibreMaxHP, a second-generation three-six axis photonics alignment platform built on the company’s ANT nanopositioning product line. It is designed for photonics alignment in an automated, nonstop production environment. This reliable drive and control technology ensures years of maintenance- free service in a high throughput manufacturing environment. FibreMaxHP is capable of 2nm linear and 0.05µrad rotary minimum incremental motion, with speeds of up to 400mm/s, to meet the challenges of aligning next-generation photonics packages. The direct-drive technology employed in FibreMaxHP offers a significant precision and throughput advantage. Aerotech’s controllers work with a variety of smart cameras and machine vision systems. The company’s power servo scanning algorithms can optimise power coupled through the devices. Standard scanning routines include fast align, hill climb, spiral and raster searches in up to six axes of motion.
The company’s advanced kinematics enable a virtual pivot point where rotation can occur at any user-defined point in space, rather than the physical rotation point of the FibreMaxHP axes. This assists the speed and accuracy of active alignment. Aerotech has an extensive array of software and hardware options to suit specific needs.
The FibreMaxHP is available with three-six Gecko series of polygon scanners
Precision Laser Scanning has announced its Gecko series of ultra-compact polygon scanners. The scanners have the motor polygon assembly mounted directly to the control board. The size of the control board has been reduced with application specific ICs. The high efficiency of the Gecko means it doesn’t need a bulky heat sink. A complete motor polygon assembly with controller can be made with a footprint smaller than a credit card.
Potential applications for the Gecko scanners include microscopy and biomedical systems, which have always had size constraints. In addition, as UAVs get smaller, polygon scanners
axes of direct-drive alignment, allowing the platform to be specified with the exact number of axes needed for the application. Since many applications require manual adjustment of fixtures and parts for a one-time initial alignment, the FibreMaxHP comes with one-three axes of manual angular alignment with ±2° of motion. These manual adjustment axes mount directly
to the direct-drive platform and offer a more economical approach to alignment when adjustment is not frequently required. The FibreMaxHP is a modular design that can be customised with a special arrangement of axes, fixturing, and mounting patterns to meet the needs of a specific application.

used for lidar (light detection and ranging) must be reduced in size, weight and power consumption, while autonomous vehicles including self-driving cars may use compact polygon scanners for collision avoidance. The small size and low mass of a Gecko polygon scanner is optimal to put it at the end of a rapidly moving robotic arm. Ultrafast lasers require polygon speed to use megahertz pulse rates fully in material processing. Gecko scanners are available in custom sizes and speeds with any number of facets to meet OEM requirements for high speed laser scanning.
