Overview
The Dantsin OMT Series Flash Metrology Systems are high-speed, non-contact 2D optical measurement instruments engineered for precision dimensional inspection in industrial production environments. Based on telecentric imaging metrology principles, these systems utilize dual-magnification, bilateral telecentric optics with exceptional telecentricity (≤0.05° chief ray angle deviation), enabling accurate measurement of parts with surface height variations (step differences) without Z-axis repositioning or manual alignment. Unlike conventional coordinate measuring machines (CMMs) or vision systems requiring part fixation and orientation, the OMT flash metrology platform supports direct placement of components onto the motorized granite stage—no fixture, no leveling, no iterative setup. Measurement is executed in a single camera exposure (<150 ms per frame), delivering full-field 2D geometric data—including distances, angles, radii, positions, and form deviations—in real time. The system architecture integrates a high-resolution monochrome CMOS sensor (≥5 MP), LED-strobed coaxial and ring illumination modules, and thermally stabilized optical pathways to ensure long-term repeatability under ambient workshop conditions.
Key Features
- Dual-magnification telecentric optical path: Switchable between high-accuracy low-magnification (e.g., 0.5×) for large-field coverage and high-resolution high-magnification (e.g., 2.0×) for fine-feature analysis—both maintaining sub-pixel edge detection stability.
- Zero-alignment operation: Parts placed freely on the stage are automatically localized via fiducial-based pattern recognition; no manual leveling or rotational adjustment required prior to measurement.
- Real-time measurement engine: Full 2D geometric evaluation completed within 300 ms from trigger—optimized for inline and near-line quality control in high-volume manufacturing.
- Thermal drift compensation: Embedded temperature sensors and adaptive pixel calibration algorithms maintain measurement consistency across ambient fluctuations (18–28 °C operating range).
- Ruggedized industrial design: IP54-rated enclosure, vibration-damped granite base, and ESD-safe stage surface compliant with ISO 14644-1 Class 8 cleanroom compatibility for medical device and electronics applications.
Sample Compatibility & Compliance
The OMT Series accommodates flat, slightly warped, or stepped 2D parts with maximum dimensions up to 300 mm × 300 mm (Model 3020) or 200 mm × 200 mm (Model 2020), including PCBs, stents, stamped metal brackets, injection-molded housings, and laser-cut gaskets. Transparent, reflective, or matte-surface materials are supported via configurable lighting modes (backlight, coaxial diffuse, oblique ring). All measurement routines comply with ISO 15530-3 (calibration using calibrated workpieces) and support traceable uncertainty reporting per ISO/IEC 17025 requirements when paired with NIST-traceable calibration artifacts. System validation documentation satisfies internal QA protocols aligned with IATF 16949 clause 7.1.5.2 and ISO 13485 section 7.6 for medical device manufacturers.
Software & Data Management
OMT VisionMaster™ software provides an intuitive, icon-driven interface with drag-and-drop measurement sequence programming. Users define geometric features (e.g., “circle Ø12.5 ±0.02 mm”, “distance between two parallel edges”) via graphical annotation—no scripting or coding required. Each program stores full image metadata, measurement logs, and statistical process control (SPC) parameters (X̄, R, Cp/Cpk) in encrypted SQLite databases. Audit trails record operator ID, timestamp, measurement values, pass/fail status, and software version—fully compliant with FDA 21 CFR Part 11 for electronic records and signatures. Export formats include CSV, PDF reports (with GD&T callouts), and XML for MES/ERP integration (Siemens Opcenter, Rockwell FactoryTalk).
Applications
- Electronics: SMT stencil aperture verification, connector pin pitch and coplanarity, flex circuit fiducial alignment tolerance.
- Medical Devices: Stainless-steel surgical instrument blade width and edge radius, nitinol stent strut thickness uniformity, catheter hub concentricity.
- Automotive: Brake pad chamfer angle consistency, bracket hole position GD&T (TP, POS), gear tooth profile deviation screening.
- Plastics & Precision Machining: Mold cavity replication fidelity, insert-molded metal part location shift, threaded insert depth verification.
FAQ
What is the typical measurement uncertainty for the OMT 3020 at 2× magnification?
Uncertainty is specified as ≤±1.2 µm (k=2) for length measurements under controlled lab conditions (20 ±0.5 °C, ISO 22028-1 lighting); field performance in shop-floor environments typically achieves ≤±2.5 µm.
Can the system measure parts with mixed material finishes (e.g., anodized aluminum + painted plastic)?
Yes—adaptive illumination sequencing and dynamic thresholding in VisionMaster™ allow consistent edge detection across heterogeneous reflectivity without manual parameter tuning.
Is GLP/GMP audit trail functionality included by default?
Yes—user authentication, electronic signature capture, and immutable measurement history logging are enabled out-of-the-box and configurable to meet 21 CFR Part 11 Subpart B requirements.
Does the system support automated pass/fail decision logic based on GD&T tolerances?
Yes—tolerance zones (e.g., position, profile, symmetry) are defined graphically during programming; results are color-coded (green/red) and exported with annotated deviation vectors.
What calibration standards are recommended for routine verification?
Dantsin-certified ceramic step gauges (NIST-traceable) and photomask-based reticles with certified line widths (e.g., 5 µm, 25 µm, 100 µm) are supplied with each system and validated annually per ISO 17025-accredited service providers.
