Product Overview
High Transparent AR (Anti-Reflective) Optical Lens LSR is a specialized two-part liquid addition-cure silicone rubber developed by 橡楚(湖北)橡胶有限公司 specifically for optical lens applications requiring premium light transmission and anti-reflective performance. As a professional manufacturer of Liquid Silicone Rubber products based at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号, we formulate this material to address the critical performance gaps of conventional optical polymers: inconsistent light transmission, poor UV resistance, and surface degradation over long-term use.
This LSR product is designed to be directly molded into AR optical lens blanks or coated as a functional anti-reflective protective layer for glass and polycarbonate lenses. It features an optimized molecular structure that reduces surface reflection, enhances visible light transmittance, and maintains stable optical performance across a wide temperature range. Unlike general-purpose transparent silicones, our High Transparent AR Optical Lens LSR is refined to eliminate residual micro-bubbles and volatile impurities that compromise optical clarity, delivering consistent performance for precision optical applications.
Our formulation is customizable to match specific hardness, refractive index, and molding requirements, supporting both high-volume mass production and small-batch custom optical component manufacturing.

Product Advantages
1. Optimized Optical Performance for AR Applications
Our proprietary refining process removes micro-impurities and bubble nucleating agents that cause light scattering, resulting in 2-3% higher visible light transmittance than standard transparent silicones. The controlled refractive index and low surface energy formulation naturally reduce surface reflection without requiring additional complex coating processes for entry-level AR applications, lowering overall production costs for optical component manufacturers.
2. Excellent Environmental Stability
Unlike optical-grade polycarbonate and acrylic materials, High Transparent AR Optical Lens LSR retains its transparency and optical properties after long-term exposure to UV radiation and extreme temperatures. It does not yellow or crack after 1000 hours of UV accelerated aging testing, making it suitable for long-term outdoor use. It also resists common optical cleaning chemicals, skin oils, and moisture, maintaining performance over extended product lifecycles.
3. High Design Flexibility for Molding
As a low viscosity liquid material, this LSR easily fills complex mold cavities with thin wall sections, enabling production of custom-shaped and free-form AR lenses that are difficult to achieve with glass or rigid polymers. The low linear shrinkage rate (≤0.3%) ensures consistent dimensional accuracy for precision optical assemblies, reducing post-molding processing requirements and scrap rates.
4. Biocompatible Option Available
We offer food-contact and skin-contact compliant grades of this LSR that meet international safety standards, making it suitable for wearable optical devices that come into prolonged contact with human skin.
Applications
High Transparent AR Optical Lens LSR is used across a range of precision optical industries:
Consumer Electronics: AR (Augmented Reality) and VR (Virtual Reality) headset lens components, smartphone camera lens protective covers, screen anti-glare lens layers, and smart watch screen protection.
Automotive Optics: Head-up display (HUD) AR projection lenses, rearview mirror anti-glare coatings, and ADAS (Advanced Driver Assistance Systems) sensor cover lenses that require anti-reflective performance to reduce signal interference.
Eyewear: Safety goggle lenses, sports sunglasses protective layers, prescription insert lenses for smart glasses, and reading glass lenses for low-cost optical applications.
Photography and Imaging: Camera lens filter layers, drone imaging camera protective covers, and surveillance camera dome covers that reduce glare and improve image clarity.
Medical Optics: Disposable endoscope lens covers, surgical microscope protective lenses, and vision correction device components where biocompatibility is required.
Selection Guide
Hardness Selection
Hardness is selected based on your specific application and processing method:
20-30 Shore A: Suitable for flexible anti-reflective coating layers, adaptive AR lenses for wearable devices, and curved lens surfaces requiring conformability.
40-50 Shore A: General purpose option for injection molded AR lens blanks, most consumer electronics and automotive optical applications.
60-70 Shore A: Recommended for high-precision fixed-focus lenses, structural optical components that require high dimensional stability.
