FAQs
1. What is your MOQ for optical germanium lens?
Our standard MOQ is 50 pieces for regular production.
For small orders (≤50 pcs), we can still accept production and provide full inspection reports and measurement data for each piece upon request.
2. Do you support small batch or prototype orders?
Yes. We support small batch and prototype production for testing and evaluation before mass production.
3. What is your production lead time?
- Standard polished fused silica windows: 4–5 weeks
- Coated optical windows (AR / HR): 5–6 weeks, depending on coating type and specifications
4. Do you provide inspection reports?
Yes. We provide quality inspection reports based on order quantity:
- ≤50 pcs: Full inspection data for each piece available
- 100–1,000 pcs: 5%–10% random sampling inspection reports
- >1,000 pcs: 0.5% sampling inspection reports
All inspection data includes dimensional and surface quality parameters.
