ZOLIX HawkEye-1300 Non-Contact Line-Scanning Spectral Confocal 3D Profilometer

Overview

The ZOLIX HawkEye-1300 is a high-speed, non-contact 3D surface profilometer engineered for precision geometric metrology in advanced manufacturing environments. It operates on the principle of spectral confocal line scanning — a robust optical technique that leverages wavelength-encoded axial focus detection to achieve micron-level vertical resolution without mechanical Z-axis movement. Unlike point-scanning confocal systems or interferometric profilers, the HawkEye-1300 acquires full-line profiles in real time, enabling rapid topographic reconstruction of complex microstructures with high fidelity and minimal thermal drift. Designed specifically for inline and lab-based quality control in electronics, semiconductor packaging, optical component fabrication, and precision molding, it delivers traceable, repeatable 3D morphology data under ambient factory conditions — eliminating the need for vibration-isolated tables or climate-controlled chambers.

Key Features

• Non-contact measurement — eliminates probe wear, surface deformation, or contamination risk on delicate substrates including silicon wafers, OLED panels, and thin-film-coated lenses.
• High-speed spectral confocal line scanning — up to 1000 lines per second with 1 µm vertical resolution and ±0.3 µm repeatability over full Z-range (1.3 mm).
• Optimized for challenging surfaces — accurately measures transparent, semi-transparent, highly reflective, and high-contrast materials (e.g., AR-coated glass, sapphire, polymer films) without calibration artifacts.
• Modular optical head — compact footprint (460 × 300 × 140 mm), 5 kg mass, and integrated Ethernet interface enable seamless integration into automated inspection stations or portable metrology carts.
• Open architecture — native support for third-party automation via TCP/IP and comprehensive SDK (C/C++, Python, LabVIEW) for custom GUI development, PLC synchronization, and MES/SCADA integration.

Sample Compatibility & Compliance

The HawkEye-1300 is validated for use across diverse sample classes: planar and freeform micro-optics, molded plastic housings, wafer-level interconnects, conformal coated PCBs, and multilayer dielectric stacks. Its spectral confocal design inherently accommodates refractive index variations across layered media — enabling quantitative thickness profiling of optical thin films (e.g., SiO₂/TiO₂ antireflection stacks) with sub-micron accuracy. The system meets CE safety directives (2014/30/EU EMC, 2014/35/EU LVD) and supports GLP-compliant operation through audit-trail-enabled software logging. While not FDA 21 CFR Part 11 certified out-of-the-box, its data export protocols (CSV, HDF5, .STL) and timestamped raw profile archives are compatible with validated QMS workflows adhering to ISO 9001, IATF 16949, and ISO/IEC 17025 requirements.

Software & Data Management

The bundled HawkEye Control Suite provides real-time visualization of height maps, cross-sections, roughness parameters (Sa, Sq, Sz per ISO 25178-2), and volume calculations (e.g., glue bead volume, step height, cavity depth). All measurements are stored with embedded metadata: acquisition timestamp, environmental temperature/humidity (optional sensor input), operator ID, and instrument calibration status. Raw spectral intensity profiles are retained for retrospective reanalysis. Export formats include ASCII CSV (for SPC charting in Minitab/JMP), binary HDF5 (for MATLAB/Python post-processing), and industry-standard .STL for CAD comparison (GD&T analysis via PolyWorks or Geomagic Control X). Audit logs record user actions, parameter changes, and calibration events — supporting ISO 13485 and automotive PPAP documentation.

Applications

• Precision mechanical components — 3D contour mapping of micro-gears, stents, and injection-molded connectors; segment height verification and form error quantification (flatness, curvature, waviness).
• Advanced packaging — solder bump coplanarity, underfill fillet geometry, and die attach void detection on flip-chip assemblies.
• Optoelectronics — surface defect classification (scratches, pits, particles) on curved 3D glass covers (e.g., smartphone front panels); radius-of-curvature validation.
• Semiconductor process control — trench depth uniformity, etch profile asymmetry, and photoresist thickness variation across 200 mm/300 mm wafers.
• Thin-film metrology — non-destructive, single-shot thickness measurement of transparent dielectric layers (up to 5 stacked interfaces) with nanometer-level sensitivity to optical path difference.

FAQ

What distinguishes spectral confocal line scanning from traditional point-scanning confocal profilers?
Line scanning eliminates sequential point positioning, reducing measurement time by >90% for wide-area surveys while preserving axial resolution. It also avoids piezo-stage hysteresis and thermal drift associated with mechanical Z-scan mechanisms.
Can the HawkEye-1300 measure transparent multilayer structures like AR coatings?
Yes — its broadband spectral detection resolves multiple interference peaks from individual layer interfaces, enabling simultaneous thickness and refractive index estimation for up to five dielectric layers.
Is the system suitable for in-process monitoring on production lines?
Absolutely — the ruggedized optical head, GigE Vision compliance, and deterministic scan timing (jitter < 1 µs) make it deployable in AOI stations synchronized with conveyor motion or robotic handling.
Does ZOLIX provide NIST-traceable calibration services?
Yes — optional annual calibration includes step-height standards (NIST SRM 2160a), roughness artifacts (NIST SRM 2161), and certified Z-axis linearity reports issued per ISO/IEC 17025-accredited procedures.
How is data integrity ensured during long-duration automated inspections?
All acquisitions are checksum-verified, written to redundant storage paths, and tagged with SHA-256 hashes. Software enforces write-once-read-many (WORM) archive policies when configured for regulated environments.
