I Customer Provides Optical Requirements:
1. Lens dimensions;
2. Optical requirements (beam angle specifications), target IES file is preferred if available;
3. Luminous efficacy requirements;
4. LED light source model;
5. Assembly drawing;
6. Lens material requirement (PC or PMMA);
7. Application scenario;
8. Other special requirements.

II Optical Design Report:
BFO Optics's outstanding optical design team will develop lenses based on customer's optical requirements. The design process is typically completed within 2-5 working days, and a detailed design report will be submitted to the customer upon completion.

2. No conflicts between the lens structure and the luminaire structure;
3. No conflicts between the lens structure and component positions;
4. Confirmation of other relevant information.

V Mold Product Quotation:
1. Pricing depends on mold size and product complexity;
2. Quotation includes formal mold cost and prototype mold cost(Prototype mold is optional, determined by mold complexity).

VI Customer's Mold Order:
After quotation confirmation, the customer issues a formal purchase order contract.

VII Payment:
BFO Optics provides proforma invoice and payment details. Mold production will commence upon receipt of full payment.

VIII Mold Manufacturing Production:
Mold production requires 30-35 working days. After mold completion, trial molding will be conducted, and sample products will be shipped to the customer for inspection.

IX Sample Approval:
Customer confirms and approves the sample, verifying that the optical performance and structure fully comply with the design specifications.

X Mass Production:
If the sample passes inspection, the process proceeds as follows:
1. Customer places mass production order;
2. BFO Optics prepares proforma invoice;
3. Customer makes payment;
4. BFO Optics initiates mass production.
