Optical Glass Polishing can be reviewed for Sensor Window Glass, but the accepted route depends on the exact grade or functional material definition, supplied form, thickness, feature geometry, edge condition, surface requirement and inspection method. The assigned process record notes: Optical Glass Polishing: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. The assigned material or application record adds: Bandpass, angular response, humidity resistance, seal compatibility and package CTE determine the substrate.

How the Process and Glass Type Interact
The table separates verified process or material records from project-specific items that still require drawing review.
| Review area | Assigned technical basis |
|---|---|
| Process purpose | Optical Glass Polishing: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. |
| Material or functional basis | Bandpass, angular response, humidity resistance, seal compatibility and package CTE determine the substrate. |
| Input form | Flat sheet, blank, tube, rod or preform as applicable to the named process |
| High-risk condition | Thin, brittle, strengthened, crystalline or coated parts require grade- and geometry-specific qualification |
| Inspection basis | Dimensional and visual inspection; add microscopy, profilometry or interferometry when the drawing requires it |
Material Grade Must Be Confirmed from the Installed Function
Sensor Window Glass does not identify one universal glass composition. The assigned application basis is: Transmit the sensor band while protecting the detector or MEMS element from moisture, chemicals, particles and impact. The assigned component basis is: Borosilicate, alkali-free glass, fused silica, sapphire, filter glass, silicon or germanium according to sensor band. The RFQ should therefore name the actual material grade or provide the operating requirements needed for selection.

Inspection Focus for Sensor Window Glass Optical Glass Polishing Feasibility Review
Acceptance should connect the drawing characteristic to a measurement method, fixture condition and stated limit.
| Review item | Project-specific focus |
|---|---|
| Process defects | Chipping, cracking, subsurface damage, dimensional error, contamination or surface defects as applicable |
| Process limitation | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
| Design condition | Define material grade, thickness, geometry, edge distances, datum scheme, surface/edge acceptance and inspection method |
| Product design risk | Wrong band material, angular spectral shift, humidity ingress, coating damage and housing-induced stress |
| Product inspection | Spectral/angular transmission, surface quality, dimensions/TTV, coating adhesion and environmental seal testing |
| Application failure modes | Wrong spectral glass, coating shift, moisture ingress, seal fracture, fogging and housing-induced stress. |
| Application inspection | Spectral/angular transmission, dimensions/TTV, surface quality, coating adhesion and environmental leak testing. |
