Custom PET lens spacer rings for optical assemblies
Metrixnano manufactures PET lens spacer rings to customer drawings for camera modules, lens assemblies and other precision optical components. The ring geometry helps establish the specified separation between components within an optical assembly.
We review the PET material grade, thickness, inner and outer diameters, edge requirements and assembly conditions before confirming the manufacturing route and quotation.
Specify the ring for your assembly
| Requirement | Information to provide |
|---|---|
| Material | PET (polyethylene terephthalate), with required grade, film specification or approved equivalent. |
| Geometry | Inner diameter, outer diameter, thickness, profile and drawing revision. |
| Critical tolerances | State thickness variation, flatness and dimensional acceptance limits for your assembly. |
| Surface and edges | Define burr, particle, cleanliness and cosmetic requirements, where relevant. |
| Quantity | Prototype quantity, batch size and expected repeat demand. |
| Delivery | Typical lead time is approximately one week; material availability, complexity, quantity and inspection requirements can change the schedule. The quotation confirms the project timing. |
Drawing review and inspection
Send a dimensioned PDF and, where available, the matching CAD file. Identify the dimensions that control optical alignment or spacing. Inspection methods and the required documentation are agreed for the specific part before manufacture.
The achievable tolerance for a thin PET ring depends on its material and geometry. A general machining precision figure should not be treated as an automatic tolerance for every spacer-ring feature.
Frequently asked questions
Can you manufacture a custom inner and outer diameter?
Submit the ring drawing, thickness and quantity for a feasibility review and quotation. Dimensions are agreed by drawing.
What should accompany a confidential drawing?
Request an NDA before sharing confidential files. Include the material specification, drawing revision, quantity and required delivery date.
How are production capacity and tolerances confirmed?
They are evaluated for the specific ring and batch. Ask for the agreed acceptance criteria and inspection scope with your quotation.
