High Transparency Optical LSR Optical Lens is a precision-molded optical component manufactured from medical-grade, platinum-catalyzed liquid silicone rubber (LSR) by 橡楚（湖北）橡胶有限公司, located at 湖北省鄂州市鄂城区经济开发区凡口街道内河巷54号. Designed to meet the growing demand for lightweight, impact-resistant optical components across consumer electronics, medical devices, and industrial automation, our LSR optical lenses deliver exceptional light transmittance, consistent optical clarity, and reliable long-term performance in challenging operating environments.
Unlike traditional glass or rigid plastic lenses, LSR optical lenses leverage the unique elastic and optical properties of high-purity liquid silicone rubber to combine optical precision with mechanical flexibility. Our in-house injection molding process ensures tight dimensional tolerances and uniform material distribution, eliminating internal defects that can degrade light transmission. This product is developed specifically for applications requiring low haze, high light transmittance, and resistance to temperature fluctuations and UV exposure, making it a versatile alternative to conventional optical materials for both prototyping and mass production.
At 橡楚（湖北）橡胶有限公司, we focus exclusively on custom Liquid Silicone Rubber (LSR) products, and our optical LSR lenses are produced to match customer-specific dimensional and performance requirements, with consistent quality maintained through every production batch.

Our High Transparency Optical LSR is formulated from 100% pure platinum-catalyzed addition-cure liquid silicone rubber, with no added fillers that would compromise optical clarity. Key material properties are listed below:
Finished LSR optical lenses maintain consistent mechanical and optical performance across their operating range:
All our optical LSR lenses are produced via precision liquid injection molding, with controlled process parameters to ensure optical consistency:

Our high-purity LSR formulation eliminates the light scattering caused by filler particles, delivering visible light transmittance comparable to many common optical plastics while retaining the inherent flexibility of silicone. The low haze and consistent refractive index ensure sharp, undistorted light transmission for imaging and light guiding applications.
Unlike brittle glass lenses and rigid polycarbonate lenses, LSR optical lenses are inherently elastic and impact-resistant, making them highly resistant to cracking and chipping during handling, installation, and end-use. This durability reduces product failure rates and extends service life in portable and rugged applications. LSR also resists UV degradation and thermal yellowing far better than most organic optical polymers, maintaining optical clarity after years of outdoor or high-temperature exposure.
Our precision LSR injection molding process supports complex, custom lens geometries including aspheric surfaces, Fresnel patterns, and integrated mounting features that are difficult or costly to achieve with glass machining. We can produce lenses in small prototype batches and high-volume production runs, with the ability to adjust hardness, size, and surface finish to match specific customer requirements.
Our optical LSR material is free of leachable peroxides and harmful additives, meeting basic biocompatibility requirements for short-term skin contact applications. This makes our lenses suitable for use in medical diagnostic devices and wearable consumer products without additional post-processing purification for most use cases.
LSR has a lower specific gravity than glass and most optical plastics, resulting in lenses that are up to 40% lighter than equivalent glass lenses. This weight reduction is particularly valuable for portable and wearable devices, where reducing overall product weight improves user comfort.
