UV Glass
Material- and grade-dependent; qualify cutting, grinding, drilling, lapping and polishing against fracture and surface requirements
Sight Glass
Round disc, weld-on assembly window, bolted flange disc or fused metal sight-glass component
Drawing-defined feasibility
Final feasibility is reviewed against grade, supplied stock, dimensions, thickness, holes, cutouts, edges, surfaces, quantity and inspection criteria.
How the Glass Type and Product Form Fit Together
The assigned technical records separate published material or application guidance from the dimensions and acceptance criteria that remain drawing-specific.
| Review area | Assigned technical basis |
|---|---|
| Material definition | Material- and grade-dependent; qualify cutting, grinding, drilling, lapping and polishing against fracture and surface requirements |
| Product-form definition | Round disc, weld-on assembly window, bolted flange disc or fused metal sight-glass component |
| Typical materials | Tempered borosilicate sight glass, fused quartz for special optical/temperature duty, or assembly-qualified alternatives |
| Application duty | Provide continuous visual observation across a vessel, tank or pipe pressure boundary without losing containment. |
| Inspection basis | Dimensional and edge inspection, transmitted-light visual check, certificate review and assembly pressure/leak validation |
UV Grade Fused Silica 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 | UV-grade fused silica |
| Transmission range | 193 nm ArF lithography grade; full curve is grade- and thickness-specific |
| 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 disc, weld-on assembly window, bolted flange disc or fused metal sight-glass component |
| Dimensions and thickness | 30–265 mm diameter published DIN 7080 range |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Controlled ground edge compatible with the armature; no uncontrolled chips in loaded zones |
| Inspection | Dimensional and edge inspection, transmitted-light visual check, certificate review and assembly pressure/leak validation |
| 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 | Use grade-specific laser-damage, homogeneity and transmission data; do not substitute general fused-silica values |
| Drawing release | For UV Glass Sight Glass, define datums, critical features, edge and surface zones, quantity, inspection and packaging before releasing the route. |
Inspection Focus for Custom UV Glass Sight Glass Processing
Acceptance should connect every critical drawing characteristic to an instrument, fixture condition and stated limit.
| Review item | Project-specific focus |
|---|---|
| Product design risk | Incorrect pressure/temperature derating, gasket point load, chemical attack, thermal shock and edge damage |
| Product inspection | Dimensional and edge inspection, transmitted-light visual check, certificate review and assembly pressure/leak validation |
| Application failure modes | Thermal shock, gasket point loading, wrong pressure derating, chemical surface attack and edge-initiated fracture. |
| Application inspection | Dimensions, edge microscopy, transmitted-light inspection, certificate review, then assembly leak/pressure validation. |
| Acceptance method | Transmittance Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
| Feature-to-edge damage | For Custom UV Glass Sight Glass Processing, inspect chips, microcracks, breakouts and edge damage around processed features and adjacent walls. |
