Sapphire Polishing vs Glass Polishing: What’s the Difference?
The main difference between sapphire polishing and glass polishing is that sapphire is much harder, more wear-resistant, and more anisotropic than optical glass, so it usually requires more aggressive abrasives, longer processing time, tighter heat control, and more careful surface damage management. Glass polishing is generally faster and more chemically responsive, while sapphire polishing is […]
What Is Subsurface Damage in Optical Components and How to Eliminate It?
Subsurface damage in optical components refers to hidden microcracks, residual stress, embedded abrasive particles, voids, and structural defects beneath the visible surface of an optic. It is often introduced during sawing, grinding, lapping, or polishing, and it can reduce optical performance even when the surface looks smooth. For precision optics, surface roughness alone is not […]
Top 10 Questions to Ask Before Choosing a Lapping Service Provider
When selecting a lapping service provider, the stakes are incredibly high. Precision lapping is often the final stage in the manufacturing process, meaning any error can result in the loss of expensive, pre-machined components. To ensure your project meets exacting specifications for flatness, parallelism, and surface finish, you must vet your partner thoroughly. The top 10 questions […]
How to Evaluate an Optical Polishing Service Supplier: The Ultimate Checklist
To evaluate an optical polishing service supplier effectively, you must assess their technical metrology capabilities, material expertise, quality management certifications (such as ISO 9001), and their ability to meet specific surface roughness and flatness tolerances. A reliable supplier should provide interferometric data and profilometer reports to validate that components meet Angstrom-level requirements. Choosing the right partner involves auditing their production scalability, […]
