| Application duty | Transmit the sensor band while protecting the detector or MEMS element from moisture, chemicals, particles and impact. |
| Inspection basis | Spectral/angular transmission, surface quality, dimensions/TTV, coating adhesion and environmental seal testing |
Heat Resistant Glass Properties Relevant to This Product Form
Published values retain their grade and source conditions. Finished-part behavior also depends on geometry, machining, edge condition and assembly.
| Material property | Published reference |
|---|---|
| Material category | Glass-ceramic |
| Thermal expansion | 0 +/- 0.2e-6 to 1.0e-6 1/K (20 to 700 deg C; variant-dependent) |
| Service temperature | up to 950 deg C for opaque white, 1 h homogeneous heating; lower limits apply to other variants |
| 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 | Flat window, window lid, lens cap, wedged cover, coated aperture or patterned sensor cover |
| Dimensions and thickness | Package-scale windows through larger LiDAR covers; housing aperture and field of view govern |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Fine ground/chamfered outside clear aperture; sealing edge matched to hermetic or adhesive process |
| Inspection | Spectral/angular transmission, surface quality, dimensions/TTV, coating adhesion and environmental seal testing |
| 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 Sensor Window, define datums, critical features, edge and surface zones, quantity, inspection and packaging before releasing the route. |
Inspection Focus for Custom Heat Resistant Glass Sensor 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 | 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 |
| Feature-to-edge damage | For Custom Heat Resistant Glass Sensor Window Processing, inspect chips, microcracks, breakouts and edge damage around processed features and adjacent walls. |
