Choose the process before you choose the machine.

The 6D SynchroScan combines a 3-axis galvo scanner with a 3-axis EtherCAT servo platform, enabling large work areas to process in one continuous move instead of stepping through stitched tiles. Over 2x faster than stitch-scan workflows with 10 µm camera-to-laser calibration accuracy.

The Coaxial Camera views along the exact same optical path as the laser beam. Unlike external overview cameras that view from an angle, this camera looks through the galvo mirrors themselves — what the camera sees is exactly where the laser will fire. No parallax, no perspective distortion.

• 2μm placement accuracy — micrometer-precise laser alignment
• Liquid lens autofocus — electronic focus, no moving parts. When image is in focus, laser is in focus
• 3D measurement — use focus distance to measure surface height
• Best with True 3D Galvo — no f-theta lens means zero distortion in the coaxial view

A third galvo axis moves an expansion lens in a telescope configuration for true software-controlled 3D focusing at every point. Unlike "focus shifter" type 3D galvos that still need an f-theta lens, the True 3D system has no f-theta lens — eliminating field distortion entirely.

• Software-controlled focus — every point focused independently in 3D space
• No f-theta lens — no field curvature, no barrel/pincushion distortion
• Curved surface processing — engrave on non-flat objects with consistent focus
• Coaxial camera synergy — no lens distortion after mirrors means perfect vision alignment

FSL uses EtherCAT — the same industrial fieldbus used in semiconductor fab equipment and CNC machines — for real-time servo motor control. Sub-microsecond synchronization across all axes ensures smooth, precise motion at high speeds.

• Deterministic timing — guaranteed sub-microsecond cycle times
• Multi-axis coordination — XY gantry, Z-axis, rotary, and galvo all synchronized
• Industrial standard — same protocol used in semiconductor, automotive, and aerospace manufacturing
• High-speed communication — 100 Mbit/s with hardware-level synchronization

FSL's AI vision system uses machine learning to automatically detect objects on the work surface, determine their outlines, and align laser operations precisely. Combined with 3D depth cameras, the system maps surface topology for autofocus across irregular shapes.

• Automatic object detection — place parts anywhere, the camera finds them
• 3D surface mapping — ZCam captures depth at 0.1mm accuracy for autofocus
• 90 fps global shutter — real-time vision feedback during processing
• WLC calibration — Whole Lens Correction maps the full workspace to <10µm accuracy

Structured blue light 3D line scanner integrated with our 90fps Global Shutter Camera system. Projects a precision blue laser line across the work surface to capture real-time 3D surface profiles with 0.020mm Z accuracy over a 100x100mm field of view.

• 0.020mm Z accuracy — structured light triangulation for precise surface mapping
• 100x100mm field of view — captures detailed depth maps across the scan area
• 90 fps global shutter — real-time 3D profiling during processing
• Laser-aligned bounding boxes — depth data maps directly to galvo coordinates for perfect Z-compensation
• SynchroScan integration — continuous scanning during servo travel for full-area 3D capture

Whole Lens Correction (WLC) handles all lens distortions — barrel, fisheye, coma, and astigmatism — using our Shack-Hartmann wavefront sensor. The sensor measures the actual wavefront passing through the galvo lens, builds a compensation map, and corrects every coordinate in real time for the most accurate laser-to-camera placement in the industry.

• Shack-Hartmann wavefront sensor — measures barrel distortion, fisheye, coma, and astigmatism across the full field
• Sub-20μm accuracy — camera-to-laser placement verified across the entire workspace
• Full-field correction — not just center calibration; every point in the work area is compensated
• Automatic compensation map — RetinaEngrave applies corrections in real time during processing
