In industries such as glass manufacturing, optical components, and display production, dimensional inspection of transparent objects remains a persistent challenge in quality control. Traditional contact-based measurement methods risk scratching product surfaces, while laser or vision inspection systems often suffer from data distortion due to the light transmission properties of transparent materials. How can we achieve non-contact, high-precision, and efficient dimensional inspection of transparent objects?


The POMEAS HM-1065 Online Projection Measuring Instrument provides the perfect solution.


The HM series employs a high-precision optical projection system that uses structured light projection technology to project specific patterns onto the surface of transparent objects. Even when encountering highly transparent materials like glass or acrylic, the system captures differences between reflected and refracted light to generate clear 2D contour images within 35ms, automatically identifying key dimensions such as length, width, and diagonal.
1. Anti-transparency interference algorithm: Eliminates the impact of light transmission on imaging, ensuring sharp, discernible edges;
2. Sub-pixel edge extraction: Achieves ±0.005mm precision to meet precision machining requirements;
3. Dynamic projection compensation: Adapts to transparent products with varying curvatures and thicknesses.
Measurement Results:


Traditional inspection requires multiple positioning steps and manual readings, whereas the HM series achieves full-process automation:
1. Projection Imaging: After product placement, the system automatically projects a grating and completes imaging;
2. Intelligent Analysis: Real-time calculation of length and width dimensions with generation of inspection reports;
3. Data Integration: Supports integration with MES and QC systems to achieve closed-loop production management.
The HM series design balances versatility and specialization, offering a multi-material universal solution.




The HM Series Online Projection Measuring Instruments are not merely inspection tools, but a pivotal step toward intelligent and standardized manufacturing in the transparent object industry. POMEAS will continue to leverage optical technology as its core strength, delivering more efficient and precise dimensional solutions to customers worldwide.
