Have You Wished You Could Focus On Your Samples Better?
Have you ever wished for sharper, clearer focus on your samples, regardless of surface variations or dynamic conditions? AutoFocus technology offers a transformative solution, ensuring optimal focus precision for imaging and process equipment, even in challenging environments.
What Makes ACS’ Advanced Dynamic Focus Control Technology Stand Out?
At the heart of the AutoFocus solution lies a cutting-edge algorithm that dynamically maintains the ideal focus. Whether you're working with a camera, laser source, or microscope, this system bridges the gap between position control and focus quality.

- Adaptive Precision Across Uneven Surfaces
Flat surfaces are simple to focus on, but real-world applications often involve irregular terrains. AutoFocus uses a sensor-based feedback system that continually adjusts to maintain the correct distance between your equipment and the surface, ensuring consistent performance. - Innovative Sensor Integration
The system employs sophisticated sensors to measure light intensity and calculate precise focal distances. These sensors communicate real-time feedback to the controller, allowing for instantaneous adjustments and delivering unmatched clarity. - Seamless Control Loop Switching
Unlike conventional methods relying solely on encoder feedback, this technology switches between position and focus control loops. It reacts to dynamic changes by leveraging sensor-driven data, ensuring both accuracy and adaptability.
The Technology Behind the Solution
Focus Feedback Control
The AutoFocus algorithm compares the current focus position with the desired point and minimizes errors through real-time adjustments. This ensures consistent performance, even in changing environments or with unpredictable surfaces.

The light intensity indicates distance to the focal point. The distance of the lens to the ideal focal point can be calculated from the light intensity and the distance between the sensors.
Control and Quality Signals
The system processes two critical inputs:
- Control Signal: Governs focus adjustments to minimize error.
- Quality Signal: Ensures that the incoming data is robust enough for optimal functionality.

Together, these signals create a feedback system that guarantees both precision and reliability.
Versatile Signal Sources
The AutoFocus system is compatible with multiple input sources:
- Analog signals from general-purpose inputs.
- Sine/Cosine encoders for enhanced accuracy.
- SPI communication protocols, providing data-rich feedback loops.
This versatility ensures seamless integration into diverse applications.
Supported Products and Applications
AutoFocus is available across a range of ACS’ product lines, including UDM, IDM, and ECM series drives, each designed to support a single AutoFocus axis. These drives offer exceptional compatibility with various signal types, enabling tailored solutions for unique operational needs.
For compact or single-axis applications, the MDMst drive provides a focused solution with some limitations, making it an ideal choice for smaller setups.
