Custom Borosilicate Glass Protective Glass Cover

Geometry, material, edge, surface and inspection review

Borosilicate Glass can be supplied and processed as Protective Glass Cover when the exact grade or functional material duty, stock form, dimensions, thickness, edge and surface requirements are defined by the drawing. The assigned material or application record notes: Material- and grade-dependent; qualify cutting, grinding, drilling, lapping and polishing against fracture and surface requirements. The assigned product record adds: Flat cover, display cover, domed/pressed lighting cover, LiDAR cover or equipment guard window.
