| Transmission range | 400 to 800 nm chart for polished approximately 4 mm samples |
| Available forms | Flat glass-ceramic panels in transparent, tinted and opaque variants |
Geometry, Surface and Inspection Requirements
Product-family data is a planning reference. The drawing must identify the exact shape, critical zones and measurable acceptance limits.
| Product requirement | What to define |
|---|---|
| Geometry and available forms | Holes, slots, cutouts, steps, grooves, radii, chamfers, bores and optical faces |
| Dimensions and thickness | State outer dimensions, thickness, diameters, lengths, OD/ID and datum scheme as applicable. |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| 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 | Flat glass-ceramic panels in transparent, tinted and opaque variants |
| 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 Heat Resistant Glass Lighting Glass Component, define datums, critical features, edge and surface zones, quantity, inspection and packaging before releasing the route. |
Inspection Focus for Custom Heat Resistant Glass Lighting Glass Component
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 | Thermal-shock cracking, low transmission, glare, lens-pattern error, edge chips and seal leakage. |
| Application inspection | Transmission/photometry, dimensional and edge inspection, thermal-cycle/thermal-shock and fixture impact/ingress tests. |
| Acceptance method | Microscopic Edge Inspection: Compare calibrated result with the drawing, purchase order or approved test specification |
| Feature-to-edge damage | For Custom Heat Resistant Glass Lighting Glass Component, inspect chips, microcracks, breakouts and edge damage around processed features and adjacent walls. |
