Description
Custom Optical Solutions & Manufacturing Capability
We provide customized optical solutions tailored to your requirements, including spherical and flat surfaces, as well as specific focal lengths, diameters, and anti-reflection coatings. Our engineering team works closely with customers from optical design and drawing confirmation through to prototype and mass production, ensuring precise performance for demanding infrared and laser applications.
Scalable Production with Consistent Quality
With mature manufacturing processes and stable production capacity, our annual output exceeds 300,000 optical components. Every batch is produced under strict process control to ensure high consistency, repeatability, and stable optical performance for industrial-scale applications.
Competitive Cost Advantage
By leveraging large-scale production and optimized manufacturing techniques, we maintain a strong balance between quality and cost efficiency. This allows us to offer highly competitive pricing while meeting the quality requirements of industrial and OEM customers.
Quality Assurance & Inspection
Each batch is supplied with material certificates and inspection reports. Quality control includes sampling inspection (typically 0.5%) with key measurements such as interferometric surface testing, focal length accuracy, and centration verification to ensure compliance with optical specifications.

FAQs
1. What is your MOQ for zinc selenide (ZnSe) 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.
5. What coating options are available?
We offer:
- Anti-Reflection (AR) coatings
- High-Reflection (HR) coatings
- Broadband coatings
- Custom wavelength coatings (UV / Visible / IR)
6. Can you manufacture custom sizes and shapes?
Yes. We support OEM manufacturing according to drawings.
Available shapes include:
- Round
- Square
- Rectangular
- Stepped
- Wedged
- Drilled / special structures
7. What quality certifications do you have?
We are certified under international quality management systems, including:
- ISO 9001 Quality Management System
- IATF 16949 Automotive Quality System
- Good Standardization Practices Certification
We also apply strict internal quality control processes, including dimensional inspection, surface quality testing, and coating performance verification before shipment.
