Sensor Glass Window
Transmit the sensor band while protecting the detector or MEMS element from moisture, chemicals, particles and impact.
Sensor Window Glass Technical and Selection Notes
Sensor Window Glass is a functional glass family rather than one fixed chemical composition. The RFQ must identify the actual material or grade before thermal, optical or mechanical values are treated as acceptance criteria.
| Definition area | Project-specific reference |
|---|---|
| Component family | Sensor Glass Windows |
| Typical materials | Borosilicate, alkali-free glass, fused silica, sapphire, filter glass, silicon or germanium according to sensor band |
| Shapes and geometry | Flat window, window lid, lens cap, wedged cover, coated aperture or patterned sensor cover |
| Thickness reference | Project-specific; thickness affects transmission, focus, seal stress and impact resistance |
| Size reference | Package-scale windows through larger LiDAR covers; housing aperture and field of view govern |
| Hole and slot options | Usually avoided in clear aperture; alignment tabs, patterned coatings or seal lands may be required Usually avoided in clear aperture; alignment tabs, patterned coatings or seal lands may be required |
| Edge options | Fine ground/chamfered outside clear aperture; sealing edge matched to hermetic or adhesive process |
| Surface options | Low scatter, controlled TTV/wedge, band-specific transmission and coating cosmetics |
| Installed function | Transmit the sensor band while protecting the detector or MEMS element from moisture, chemicals, particles and impact. |
How the Drawing Changes the Processing Plan
Base pages do not assign one universal process or tolerance. ANTGLASS selects cutting, drilling, CNC machining, grinding, lapping, polishing, cleaning and inspection steps from the drawing.
| Planning area | What to review |
|---|---|
| Candidate operations | Precision cutting, edge finish, optical polishing, spectral coating, hermetic sealing preparation and clean packaging |
| Material response | Confirm fracture sensitivity, edge damage, surface condition and the supplied form. |
| Feature geometry | Usually avoided in clear aperture; alignment tabs, patterned coatings or seal lands may be required |
| Edge and surface finish | Fine ground/chamfered outside clear aperture; sealing edge matched to hermetic or adhesive process |
| Application conditions | Include device self-heating, ambient cycling and seal-material CTE mismatch. |
| Inspection route | Spectral/angular transmission, surface quality, dimensions/TTV, coating adhesion and environmental seal testing |
Information Required Before Quotation
State the drawing revision, exact material or approved alternatives, dimensions, quantity, feature geometry, edge and surface requirements, operating conditions and the acceptance method.
| Decision area | What to confirm |
|---|---|
| Optical function | State wavelength band, incidence cone, transmission, rejection, wavefront and allowed angular spectral shift. |
| Thermal environment | Include device self-heating, ambient cycling and seal-material CTE mismatch. |
| Chemical exposure | Humidity, salt, oils, cleaners and process gases must be matched to substrate, coating and seal. |
| Mechanical load | Vibration, impact, pressure differential and package clamp or braze load require validation. |
| Pressure or vacuum | Sensor Glass Window: Define when the component forms a pressure or vacuum boundary |
| Edge condition | Clear aperture is scratch/particle controlled; seal land must have the specified texture and chip allowance. |
| Surface condition | Clear aperture is scratch/particle controlled; seal land must have the specified texture and chip allowance. |
| Cleaning | Use particle- and film-controlled optical cleaning; verify coating compatibility and avoid residue inside the sensor field of view. |
RFQ inputs
- Sensor band/angle, clear aperture, substrate, thickness, wedge/flatness, coating, seal method, environment, impact and cleanliness

Failure Risks and Inspection Focus
Inspection is tied to the functional dimensions and surfaces shown on the approved drawing; generic catalogue values do not replace project acceptance criteria.
| Review item | Project-specific focus |
|---|---|
| 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. |
| Acceptance method | Transmittance Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
