| Application duty | Maintain a known optical path and low background while containing the sample or protecting the detector. |
| Inspection basis | Interferometry, autocollimation, scratch-dig inspection, roughness metrology and spectrophotometry |
Borosilicate 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 | Borosilicate |
| Thermal expansion | 3.3 +/- 0.1e-6 1/K (20 to 300 deg C) |
| Service temperature | 500 deg C (Less than 10 hours; manufacturer reference); 450 deg C (At least 10 hours; manufacturer reference) |
| Typical thickness | 3; 4; 5; 6; 8; 10 mm (Qingdao SSMG High Borosilicate Glass 3.3 sheet program) |
| 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 | Plane-parallel, wedged, Brewster, rectangular, round, coated or filter window |
| Dimensions and thickness | Small catalog-style apertures through custom CNC windows up to supplier equipment limits |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Fine ground, beveled/chamfered and optionally blackened |
| Inspection | Interferometry, autocollimation, scratch-dig inspection, roughness metrology and spectrophotometry |
| 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 Borosilicate Glass Analytical Instrument Window, define datums, critical features, edge and surface zones, quantity, inspection and packaging before releasing the route. |
Inspection Focus for Custom Borosilicate Glass Analytical Instrument 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 | Laser damage, coating mismatch, wedge-induced beam steering, birefringence and contamination |
| Product inspection | Interferometry, autocollimation, scratch-dig inspection, roughness metrology and spectrophotometry |
| Application failure modes | Baseline drift, bubbles, fluorescence, path-length error, solvent attack and leakage. |
| Application inspection | Spectral baseline, path-length measurement, surface inspection, dimensions and leak/flow test. |
| Acceptance method | Scratch-Dig Inspection: Compare calibrated result with the drawing, purchase order or approved test specification |
| Feature-to-edge damage | For Custom Borosilicate Glass Analytical Instrument Window Processing, inspect chips, microcracks, breakouts and edge damage around processed features and adjacent walls. |
