Silicon Lens
Elyonoptics silicon lenses feature precision-polished surfaces and high-transmittance coatings, making them highly suitable for various infrared applications. We can provide plano-convex, plano-concave, biconvex, biconcave, and meniscus shapes, as well as customized options for 3μm-5μm, 5μm-8μm, ranges.
Description
Elyonoptics silicon lenses are specifically designed for infrared applications (3-5μm mid-wave infrared MWIR and 8-14μm long-wave infrared LWIR). Silicon material exhibits high transmittance, high refractive index, and excellent thermal stability in the infrared spectrum, making it an ideal choice for thermal imaging, gas detection, infrared temperature measurement, and lidar systems.
Customization Capability: Whether your requirements involve spherical, flat surfaces, or specific focal lengths, diameters, or coatings (anti-reflection films), we can closely collaborate with you to provide precise customized solutions—from design drawings to mass production.
Scalable Production Capacity and Quality Assurance: With mature and efficient manufacturing processes, our annual output exceeds 6 million pieces, ensuring exceptional consistency and repeatability for every batch to meet your large-scale production demands.
Cost Efficiency: Leveraging our extensive production scale and refined craftsmanship, we guarantee high quality while offering highly competitive pricing, significantly reducing your costs.
Support: We can provide material certifications for each batch and inspection reports at a 0.5% sampling rate (including interferometer surface profile testing, focal length/eccentricity measurements, etc.).

FAQs
1. What is your MOQ for optical silicon 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.
