Multi-Axis Light Collimation System (SSMI-04)
The Challenge

Light collimation and beam steering systems used to manufacture all of the world’s memory and logic chips require the motion of multiple motion axes in a tightly constrained space. Traditional dual sided linear motors are too large and the 200-500 g payloads common to these systems do not require large amounts of force to move. Travel lengths of a few cm are required but voice coil motors and actuators are typically limited to a few mm of travel.

The Solution

Celera Motion Javelin single sided air core linear motors offer the ideal combination of miniature footprint, extremely smooth motion, and travel lengths of several cm. Taking advantage of their low profile (<12 mm is available) and single sided construction, the Javelin Series motors can be mounted in extremely close proximity to each other.

The Benefit

Multi-axis light collimation and beam steering mechanisms designed with Javelin Series single sided motors allow OEMs to design smaller and lighter systems than similar mechanisms designed with traditional linear motors. With Javelin Series linear motors, customers have also achieved the travel lengths required that they could not realize with typical voice coil motors.
