Sight Glass Disc
Solid round disc, annulus, center-hole disc, multi-hole disc or stepped disc
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 | Solid round disc, annulus, center-hole disc, multi-hole disc or stepped disc |
| Typical materials | BOROFLOAT 33, fused silica, soda-lime float, optical filter glass or sapphire selected by wavelength and environment |
| Application duty | Provide continuous visual observation across a vessel, tank or pipe pressure boundary without losing containment. |
| Inspection basis | Diameter and thickness measurement, concentricity/runout check, edge microscopy, transmitted-light cosmetic inspection and flatness when functional |
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 | Solid round disc, annulus, center-hole disc, multi-hole disc or stepped disc |
| Dimensions and thickness | 6.35–304.8 mm published circle-grinding diameter range; larger discs require route review |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Seamed, ground, pencil-ground, polished or chamfered according to mounting and handling risk |
| Inspection | Diameter and thickness measurement, concentricity/runout check, edge microscopy, transmitted-light cosmetic inspection and flatness when functional |
| 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 Disc, define datums, critical features, edge and surface zones, quantity, inspection and packaging before releasing the route. |
Inspection Focus for Custom UV Glass Sight Glass Disc Processing
Acceptance should connect every critical drawing characteristic to an instrument, fixture condition and stated limit.
| Review item | Project-specific focus |
|---|---|
| Product design risk | Center-hole breakout, edge chips, wedge, mounting point load and thermal-gradient fracture |
| Product inspection | Diameter and thickness measurement, concentricity/runout check, edge microscopy, transmitted-light cosmetic inspection and flatness when functional |
| 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 | Scratch-Dig Inspection: Compare calibrated result with the drawing, purchase order or approved test specification |
| Feature-to-edge damage | For Custom UV Glass Sight Glass Disc Processing, inspect chips, microcracks, breakouts and edge damage around processed features and adjacent walls. |
