Subsurface 2DBC Marking & Reading
1. To mark invisible 2D barcode inside glasses / sapphires
- marking dot diameter: 2.5 μm～7.5 μm (customizable)
- barcode size: 0.1mm×0.1mm / 0.2mm×0.2mm (customizable)
- CT ≤ 3s (with auto-loading & unloading)
2. Invisible, no trace or touch feeling on the surface
3. 100% reading rate (sapphire, polished / gross CG)
4. Negligible influence on strength (can still pass 3PB and ROR strength tests after marking)
5. Barcodes remain invisible and readable after decoration
6. Real-time power monitoring and compensation
7. On-line measurement and accurate control of code depth
Advantage
1.Customized lighting and lens system
- Highly enhance the code contrast & level of sensitivity
- Allow lower laser energy and less substrate strength impact
- Improve ability to measure code depth
2. Special developed algorithm
- Robust & fast image processing algorithm to digitally enhance contrast
- More flexibility and feasibility in image processing and decoding (compared with off-the-shelf code reader)
3.Wide readable Z range for easy code reading
4.Narrow DOF for accurate depth measurement
5.Accurate & cost-effective code depth measurement (to be patented)
- Self-developed automatic z-scanning
- Self-developed indicator (LC value) calculates the best code depth
