| Refractive index | 1.47140 index (587.6 nm) |
| Available forms | Sheet, plate, disc, window, tube, rod or blank where the named grade is supplied in that form |
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 | Round, square, rectangular, wedged, stepped, flanged or drilled window |
| Dimensions and thickness | Small sensor windows through CNC rectangles up to 600 × 1000 mm supplier reference limits |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Fine ground, seamed, polished or chamfered; pressure and optical windows need controlled edge damage |
| Inspection | CMM or optical comparator, autocollimator or interferometer, transmitted-wavefront test, scratch-dig inspection and spectral test |
| 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 Borofloat Glass Appliance Glass Window, define datums, critical features, edge and surface zones, quantity, inspection and packaging before releasing the route. |
Inspection Focus for Custom Borofloat Glass Appliance Glass Window Processing
Acceptance should connect every critical drawing characteristic to an instrument, fixture condition and stated limit.
| Review item | Project-specific focus |
|---|---|
| Product design risk | Wedge-induced beam deviation, coating damage, edge-load fracture, seal stress and incorrect spectral material |
| Product inspection | CMM or optical comparator, autocollimator or interferometer, transmitted-wavefront test, scratch-dig inspection and spectral test |
| Application failure modes | Chemical etching, thermal shock, path contamination, tube-end chips and seal leakage. |
| Application inspection | Dimensions, visual cleanliness, spectral baseline, leak test where fluidic and thermal-cycle validation. |
| Acceptance method | Scratch-Dig Inspection: Compare calibrated result with the drawing, purchase order or approved test specification |
| Feature-to-edge damage | For Custom Borofloat Glass Appliance Glass Window Processing, inspect chips, microcracks, breakouts and edge damage around processed features and adjacent walls. |
