YGO ZMI‑4004 (Part Number 4S019‑765) Product Overview
- Product Positioning
The ZMI‑4004 is a 4‑axis VME64x measurement board offered by Zygo (now part of AMETEK’s ultra‑precision technology division). It is designed for high‑precision displacement/distance measurement and is widely used in semiconductor lithography, optical fabrication, metrology, aerospace, and high‑precision motion control applications.
- Core Technology and Specifications
- Resolution: Dual‑channel (2‑pass) up to 0.15 nm, single‑channel (1‑pass) about 0.31 nm.
- Measurement Speed: Up to 2.55 m/s (2‑pass); single‑channel 5.1 m/s.
- Data Rate: 10 MHz, data age uncertainty ±0.1 ns.
- Axes: Each board supports synchronized measurement on 4 axes, suitable for multi‑axis systems.
- Electronics Form Factor: 6U VME 64x, providing both parallel VME and high‑speed serial data interfaces.
- Laser Source: Paired with Zygo 7712 laser head, output power >1.35 mW, wavelength stability 0.5 ppb (1 h).
- Modularity and Compatibility
- Modular design allows installation in VME chassis and supports expansion up to 64 measurement axes.
- Seamlessly compatible with other Zygo DMI (Displacement Measuring Interferometer) components such as interferometers and fiber‑coupled modules, facilitating the construction of complete displacement‑measurement systems.
- Key Functions
- Sub‑nanometer Displacement Measurement: Achieves nanometer‑level or sub‑nanometer resolution to meet the most demanding positioning requirements.
- High‑Speed Tracking: Maintains high accuracy on fast‑moving platforms, increasing production line throughput.
- Error Compensation: Built‑in cyclic error reduction options automatically mitigate inherent DMI non‑linearity, enhancing measurement accuracy.
- Reliability: Utilizes high‑quality electronic components suitable for harsh industrial environments, with a service life exceeding 50,000 h.
- Typical Application Scenarios
- Semiconductor Lithography: Used for wafer positioning and overlay calibration, improving overlay precision.
- Optical Component Fabrication: Real‑time monitoring of machining displacement to keep errors within the nanometer range.
- High‑Precision Motion Platforms: Works with servo systems to achieve precise positioning and high‑speed scanning.
- Research Laboratories: Provides a reliable displacement reference for precision measurement experiments.
- Product Model Correspondence
- In the domestic market, the corresponding part number is often listed as 8020‑0500‑01 (the ZMI‑4004 measurement board).
- This part number is also identified in some supply chains as 4S019‑765, used for procurement and spare‑part management.
