Electric Autofocus FA Lens 16mm C-Mount ROI Tracking for Robotic Vision

This FA series motorized industrial lens adopts built-in closed-loop stepper actuators to drive internal optical groups, delivering independent motorized control for focus and iris. Integrated with the IPRAS passive autofocus solution for randomly arranged workpieces, it supports one-touch autofocus activation and continuous real-time ROI target tracking.

The lens leverages motor-driven optical movement to achieve high-precision focus tuning, paired with optimized autofocus algorithms tailored for dynamic machine vision scenarios. Users can adjust focus and iris parameters programmatically from host PCs via USB or RS-485 interfaces. It natively connects to the IPRAS ecosystem to run fully automated inspection sequences without manual adjustments on the production floor.

Core Technical Advantages

1. Broad-range Motorized Focus Tuning: Continuous focus adjustment spanning 70 mm to 1000 mm. A single lens covers multiple object distances without physical repositioning of the camera assembly.

2. Intelligent ROI Autofocus Tracking: Works alongside the IPRAS passive autofocus system to enable one-touch autofocus and persistent closed-loop ROI tracking. Suited for applications where target depth changes dynamically, such as moving conveyors and robotic material handling stations.

3. Dual Industrial Communication Interfaces: Onboard USB2.0 and RS-485 interfaces offer interoperability with industrial PCs, PLC units and other industrial host controllers.

4. High-precision Closed-loop Focus Positioning: Rotary encoder closed-loop motor control creates stable, repeatable correlation between object distance and encoder readings, delivering sub-millimeter scale focus repeatability.

5. Ultra-low Geometric Distortion: Typical geometric distortion<0.1% 2="" for="" the="" full="">

6. High-resolution Imaging & Industrial Thermal Robustness: Supports 10-megapixel image capture and continuous operation within -20 ℃ ~ +70 ℃ ambient range, delivering stable performance for non-stop production line inspection.

Representative Application Domains

1. Random Workpiece Sorting: Accommodates variable workpiece heights on unstructured conveyor belts. The IPRAS system maintains real-time focus tracking with no requirement to reposition the camera hardware.

2. Micro-component & PCB Visual Inspection: Rapid adaptive focus response for printed circuit boards and miniature electronic parts with Z-height variation, maintaining crisp feature edges and stable defect detection performance.

3. Robot Vision for Pick & Place: Sustained ROI tracking during robotic handling cycles where target depth keeps changing, locking optimal focus throughout the full motion sequence.

4. Multi-focus Image Stacking: Capture sequential frames at incremental encoder positions via programmable stepping, compatible with software EDOF (Extended Depth of Field) image reconstruction workflows.

5. Continuous In-line Quality Inspection: Generates sharp, blur-free images for parts with fluctuating heights on moving production lines, well suited for high-speed AOI and automated quality screening.

Operational Guidelines & Precautions

· Working Distance Limits: Valid motorized focus range is 70 mm ~ 1000 mm. Reliable focusing cannot be achieved below 70 mm, and optical performance will degrade outside this range.

· Mechanical Mounting: Standard C-mount interface. Ensure coaxial alignment between the lens optical axis and camera sensor plane during installation.

· Environmental Constraints: Operate within the rated temperature window of -20 ℃ ~ +70 ℃. Avoid environments with condensation, relative humidity >85%, mechanical shock and sustained vibration to safeguard encoder integrity and autofocus reliability.

· Prohibition of Unauthorized Disassembly: Optics, gear trains and calibration parameters are pre-calibrated at factory. Any unauthorized disassembly invalidates product warranty and may lead to irreversible hardware damage.

· Accessory & Power Requirements: Deploy only original cables, driver boards and supporting software. Incorrect wiring or improper voltage input may permanently damage the lens unit.

· Power-on Origin Homing: Execute origin homing before enabling IPRAS autofocus to synchronize encoder data and guarantee accurate focus positioning.

· Mechanical Handling Note: Do not manually twist the front lens barrel while the motorized focus is running, to prevent gear abrasion and transmission system failure.

· ROI Configuration Guidance: Define ROI bounding boxes on key target features; avoid regions dominated by high-contrast backgrounds to reduce unintended autofocus triggers.
