Technical Description & Processing Capabilities |
|---|---|
| Coating | Thin-film optical deposition processes, including dielectric multilayer coatings, bandpass filters, anti-reflective (AR) coatings, mirror metallic films, and color separation dichroic filters. |
| Cutting | Precision glass profiling and shaping into squares, rectangles, circles, trapezoids, triangles, sectors, and complex custom irregular geometries. |
| Chamfering | Edge deburring and safety beveling, available in standard manual chamfering or specified angle precision CNC chamfering. |
| Edging | Surface edge profiling and finishing options, including flat ground (frosted) edge, smooth pencil round edge, and precision bevel edge. |
| Spheronization | Precision circular edging and rounding for small-diameter discs or high-tolerance circular optics utilizing cylindrical grinding processes. |
| Polishing | Optical-grade surface polishing to improve surface quality (scratch-dig specs), surface roughness (Ra), optical flatness, and wave-front parallelism. |
| Printing | Precision silk-screen printing for opaque black borders (light-shielding frames), alignment marks, logos, and custom text. |
| Thermal Tempering | Physical heat-treatment and rapid air-quenching process to enhance mechanical impact strength and thermal shock resistance, fracturing into safe granular fragments upon break. |
| Chemical Strengthening | Potassium-sodium ion-exchange salt bath treatment to significantly increase bending strength and scratch resistance without causing optical distortion. |
