Absolute Position Measurement System: ZPS System
The new ZPS™ System from Zygo Corporation is designed to measure absolute position via ultra-compact optical sensors with a resolution of 0.01 nm and less than 1 nm of non-linearity. The system is typically used for closed-loop feedback systems that require continuous streams of high-precision position data from multiple sensors to maintain precise positioning and alignment.
ZPS’ fiber-fed optical sensors do not generate heat and are insensitive to electromagnetic interference, making them ideal for use in high-precision applications such as deformable mirrors and lens positioning. Optional accessories enable automatic compensation for ambient environmental changes in real time.
Key ZPS system features include:
- Non-contact optical measurement
- Repeatable absolute position (≤ 0.5 nm, 3σ)
- High-precision system using proprietary compensation algorithms
- Scalable up to 64 channels
