| Edge and surface zones | Seamed, ground, polished, beveled, chamfered or radiused |
| Inspection | Drawing-based dimensional, visual, microscopic, surface and optical inspection |
| Packaging and handling | State cleanliness, protective film, separators, individual packing and shipping requirements. |
| Manufacturing route item | Review requirement |
|---|---|
| Supplied stock | Sheet, plate, disc, window, tube, rod or blank where the named grade is supplied in that form |
| Compatible route | Precision cutting; CNC/ultrasonic machining where qualified; grinding; lapping; polishing; cleaning; inspection |
| High-risk geometry | Grade, thickness, surface state, wavelength and temperature conditions must not be generalized |
| Drawing release | For Optical Glass Scientific Instrument Glass, define datums, critical features, edge and surface zones, quantity, inspection and packaging before releasing the route. |
Inspection Focus for Custom Optical Glass Scientific Instrument Glass Processing
Acceptance should connect every critical drawing characteristic to an instrument, fixture condition and stated limit.
| Review item | Project-specific focus |
|---|---|
| Product design risk | Unmachinable corners, insufficient edge distance, thin walls, mixed tolerance systems and inspection mismatch |
| Product inspection | Drawing-based dimensional, visual, microscopic, surface and optical inspection |
| Application failure modes | Baseline drift, bubbles, fluorescence, path-length error, solvent attack and leakage. |
| Application inspection | Spectral baseline, path-length measurement, surface inspection, dimensions and leak/flow test. |
| Acceptance method | Transmittance Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
| Feature-to-edge damage | For Custom Optical Glass Scientific Instrument Glass Processing, inspect chips, microcracks, breakouts and edge damage around processed features and adjacent walls. |
