Silicone Lens

Silicone Lens

Silicone lenses, also known as silicone LED lenses, are primarily used for LED lighting. They are made of optically clear silicone materials such as Dow Corning MS4002, MS1002, Wacker LR7601, etc. These lenses not only have a light transmittance of up to 94%, but they are also heat resistant and UV resistant, which sets them apart from traditional plastic lenses like PMMA and PC. Additionally, optical liquid silicone rubber is highly flexible and can be used to manufacture complex and micro-structure LED lenses. For OEM silicone lenses, you can contact HOPEWELL.

Features of Silicone Lens

Silicone lenses have several key features that make them a popular choice for various applications.


  • Silicone lenses are known for their excellent optical clarity, which allows for high light transmission and minimal distortion.

  • Silicone lenses are anti-yellowing and UV resistance, which makes them to be used in UV lighting.

  • Silicone lenses have a high resistance to extreme temperatures, making them ideal for use in both hot and cold conditions.

  • Silicone lenses are super flexible, which allows for the creation of complex shapes and designs.
