Active Feedback Sensor for Optical Alignment | Specifications & Integration

Product Specifications

Technical details and manufacturing context for Active Feedback Sensor

Definition

The Active Feedback Sensor is a component used in optical alignment systems, such as the Active Optical Alignment Station. It continuously monitors optical alignment parameters and provides real-time feedback signals to the control system, enabling dynamic adjustment and optimization of optical components during manufacturing or calibration processes. The sensor operates on optical detection methods, including laser interferometry, CCD imaging, or photodiode arrays, to measure alignment parameters. These measurements are converted into electrical signals and transmitted to the control system for processing and generating adjustment commands. The sensor is designed for integration into automated alignment equipment, where it supports closed-loop control to maintain precise alignment. Key specifications include a detection range of 0.1–5 m, accuracy of ±0.01 mm, response time of ≤10 ms, and an analog output signal of 4–20 mA. It operates on a 24 V DC supply (±10%) and within a temperature range of -40 to 85 °C. The housing is made of corrosion-resistant stainless steel (316L) and offers ingress protection ratings from IP54 to IP65, depending on the model. The sensor weighs ≤200 g and has compact dimensions of 30×30×15 mm. These parameters are reference values and must be verified with the manufacturer for the specific model and application. The sensor is suitable for use in cleanroom and industrial environments, but proper installation and calibration are essential for optimal performance. Regular maintenance and verification of alignment accuracy are recommended to ensure reliable operation. The sensor is not a standalone measurement device; it requires integration with a control system and appropriate software for data processing. Users should consult the manufacturer's documentation for detailed installation, operation, and maintenance procedures.

Working Principle

The Active Feedback Sensor uses optical detection methods such as laser interferometry, CCD imaging, or photodiode arrays to measure alignment parameters. It converts these optical measurements into electrical signals, typically a 4–20 mA analog output, which are transmitted to the control system. The control system processes these signals and generates adjustment commands to correct any misalignment in real time. The sensor's response time of ≤10 ms enables rapid feedback for dynamic control. The detection range of 0.1–5 m allows for flexible placement within the optical system. The sensor's accuracy of ±0.01 mm ensures precise alignment feedback. The sensor is powered by a 24 V DC supply and operates within a temperature range of -40 to 85 °C. Its housing is made of stainless steel 316L, providing corrosion resistance and durability. The ingress protection rating of IP54–IP65 ensures dust and water resistance, making it suitable for various industrial environments.
