| 1 | Optical Performance | 20% | Reflectance, absorption, scattering, surface quality, and dimensional stability under the specified laser wavelength and operating temperature. | 0–20 points based on verified test data and consistency with the buyer’s wavelength, power, and geometry requirements. | 20 |
| 2 | Ceramic Material Capability | 15% | Experience with laser-grade technical ceramics, controlled porosity, thermal expansion, thermal conductivity, and resistance to thermal shock. | 0–15 points based on material specifications, process controls, and application experience. | 15 |
| 3 | Dimensional and Surface Precision | 13% | Dimensional tolerances, flatness, concentricity, surface roughness, edge quality, and compliance with optical drawing requirements such as ISO 10110 where applicable. | 0–13 points based on inspection records, calibrated instruments, and achievable tolerances. | 13 |
| 4 | Manufacturing Process Control | 12% | Powder preparation, forming, sintering, machining, polishing, coating or finishing, traceability, and control of batch-to-batch variation. | 0–12 points based on documented process flow, in-process inspection, and corrective-action procedures. | 12 |
| 5 | Quality Management | 10% | Quality management certification, incoming inspection, final inspection, nonconformance control, calibration, and product traceability. | 0–10 points; independently verifiable ISO 9001 certification and complete inspection records receive the highest score. | 10 |
| 6 | Testing and Verification | 8% | Availability of spectrophotometers, profilometers, coordinate measuring equipment, thermal testing, and calibrated measurement reports. | 0–8 points based on internal testing depth, calibration status, and access to competent external laboratories when required. | 8 |
| 7 | Customization and Engineering Support | 7% | Ability to support custom shapes, mounting interfaces, drawings, prototypes, sample approval, design feedback, and engineering changes. | 0–7 points based on technical communication, prototype capability, and documented engineering response time. | 7 |
| 8 | Production Capacity and Delivery Reliability | 6% | Available production equipment, stated monthly capacity, lead-time performance, safety stock policy, and capacity for repeat orders. | 0–6 points based on documented capacity, historical delivery performance, and scalability. | 6 |
| 9 | Compliance and Export Documentation | 5% | Material declarations, REACH and RoHS documentation where applicable, commercial invoices, packing lists, certificates of conformity, and export support. | 0–5 points based on completeness, accuracy, and suitability of compliance documentation for the target market. | 5 |
| 10 | Commercial Value and After-Sales Support | 4% | Total cost of ownership, sample charges, packaging, warranty terms, response time, replacement policy, and technical support after delivery. | 0–4 points based on transparent quotations, reasonable commercial terms, and documented after-sales procedures. | 4 |
| Total Evaluation Score | 100% | Manufacturers are ranked by verified weighted score. Technical evidence takes priority over promotional claims. | 100 |
