Custom Optical Component RFQ Checklist for Faster Quotation

A complete RFQ helps an optical supplier evaluate feasibility, tooling, inspection and cost without filling critical gaps with assumptions. It also produces quotations that are easier to compare because each supplier is working from the same requirement set.

1. Identify the Part and Program Stage

State the part name, application and development stage: concept, feasibility, prototype, pilot or released production. Mention whether the request covers component manufacturing only or also optical design, tooling, revêtement et assemblage.

2. Provide Controlled Design Files

Include a 3D model and a readable drawing with revision identifiers. If an optical prescription, ray file or performance model is available, include the format and software version. Mark which file controls if dimensions differ.

3. Define Optical Performance

• Wavelength or spectral band
• Focal length, optical power or beam target
• Surface form and clear aperture
• Centration, decenter or wedge requirement
• Transmission, reflectance or image-quality criteria

Explain the measurement method and operating condition. A target without a test method can lead to different interpretations.

4. Specify Material and Environment

List the material family and grade or provide the performance requirements for supplier recommendation. Include temperature, humidity, UV, chemicals, impact, cleaning and expected service conditions that may affect selection.

5. Describe Surface and Coating Requirements

Mark optical, cosmetic, bonding and hidden zones. For a coating, define wavelength, angle, polarization where relevant, coated surfaces, durability and appearance criteria. Include masking requirements.

6. Explain Assembly Interfaces

Show the locating datums, mating parts, adhesive or retention method and available clearances. If optical alignment occurs during assembly, describe the adjustment range and system-level acceptance test.

7. Give Quantity and Timing Information

8. Define Inspection and Documentation

List required reports, sampling, certificates and retained records. Identify critical characteristics and any customer-supplied fixture or test equipment. Ask the supplier to state proposed inspection methods and exceptions in the quotation.

9. Request Assumptions and DFM Feedback

A useful quotation separates confirmed requirements from assumptions. Request comments on material, tolerances, gate and parting line, tooling approach, revêtement, measurement and cost drivers. Early alternatives can reduce program risk before design release.

10. Protect Revision Control

Send one RFQ package with a clear revision and file list. When requirements change, issue an updated package and ask the supplier to identify cost or schedule impact. This prevents mixed versions from reaching tooling or inspection.

Review Silver Optics’ custom optical components, quality approach and engineering capabilities before preparing your request.

Frequently Asked Questions

Can I request a budgetary quote with incomplete files?

Yes, when the missing assumptions are listed clearly. A production quotation will require a more controlled requirement set.

Should I include target pricing?

Target economics and annual volume can help the supplier evaluate suitable processes, but the technical requirement should remain explicit.

What is the fastest way to receive useful DFM feedback?

Provide the 3D model, drawing, application, material, optical target and volume together, then identify which items are open for recommendation.
