High accuracy positioning refers to the ability to determine the location of an object or device with a very high level of precision. This level of precision is achieved using a variety of techniques. Two common methods for achieving high accuracy positioning are passive alignment and active alignment. Passive alignment is also known as geometrical alignment. It's typically performed using mechanical means. Active alignment uses optical feedback from sensors to align properly. One of these methods is chosen based on application standards, requirements and costs.
Simplicity and cost effectiveness are advantages when using passive alignment. It doesn’t require complex control systems or feedback mechanisms. Passive alignment is often less expensive to implement and maintain. It’s a faster way of aligning, as it doesn’t need iterative alignment processes like active alignment does. Passive alignment is especially helpful when components being aligned have well-controlled, looser tolerances. The components need to be designed to self-align accurately. Often, this means the cost of your components are more expensive.
Active alignment uses external control systems and sensors to monitor the alignment of components in real-time. This provides great flexibility and accuracy, allowing for tighter tolerances and adjustments. Active alignment is used when precision requirements are higher or when the components’ tolerances are less predictable. IMS uses active alignment for applications such as camera, lens, LiDAR and sensor assembly.
Passive alignment offers simplicity, cost-effectiveness and speed. This makes it a suitable choice for high-precision applications where components have well-controlled tolerances. Active alignment offers higher precision and more flexibility in alignment adjustments.
