Optical LSR silicon Lenses: Durability, Flexibility, and Versatility by JOKER

LSR (Liquid Silicone Rubber) optical lenses are gaining recognition across various industries due to their exceptional durability, flexibility, and resistance to harsh environments. Unlike traditional glass or plastic lenses, LSR lenses offer a unique combination of impact resistance, chemical stability, and resistance to yellowing. They also provide excellent UV resistance, making them an ideal choice for applications where reliability and longevity are critical. These properties make LSR lenses particularly suitable for automobile and motorcycle headlight systems, where exposure to extreme conditions and the need for long-term optical clarity are essential.

Why use optical grade silicone?

Today, the development of cutting-edge high-power LED technology is facing new challenges. The new generation of LEDs will need to maintain their optimum luminescence and lumen values over time and be able to be used in micro-structural design at compact sizes; however, these requirements present a major challenge to the current optical plastic components. On the contrary, optical silica is the material that can provide optical transparency, durability, and design hyperboloid and free- form surfaces.
The advantageous properties of silicone gel materials
High light transmission Can meet the design requirements of transparency, atomization, and astigmatism, with excellent results.
Luminous flux loss In the hot and humid environment, can maintain a variety of lens projection accuracy.
Durability UV resistance and crack resistance is very good; high temperature stability, showing that it can maintain a good long-term luminescence, and will not cause problems such as heat-resistant plastic yellowing.


LSR optical lenses are lightweight and flexible, allowing for innovative designs that can adapt to various shapes and sizes. This flexibility not only enhances comfort in wearable devices but also ensures a secure fit in applications where a precise seal is necessary,

Feature Overview of LSR silicone lens:
