In the manufacturing of optical devices, poor light transmittance and disordered light refraction are key issues affecting optical efficiency. Whether for secondary optical lenses, light guide pillars, or automotive lighting components, the optical performance of the material directly determines the final application effect. With outstanding optical properties — 92% high light transmittance and a uniform refractive index of 1.41 — this optical liquid silicone rubber has become an ideal partner for producing optical devices, ensuring smoother light transmission and maximizing the light efficiency of various optical products. It stands out among similar materials for its exceptional optical performance. All six models are colorless and transparent. Tested at a wavelength of 450 nm and a thickness of 2 mm, the light transmittance remains stable at 92%, meaning light passes through the material with almost no absorption or blockage, avoiding uneven transmission or haziness. What’s more, the entire series features a consistent refractive index of 1.41, providing highly uniform light refraction. This perfectly matches the optical design of secondary optical lenses and light guide devices, eliminating light loss caused by refractive index deviation at the source. It delivers higher light-guiding efficiency for pillars and more precise focusing and diffusing effects for lenses. This silicone also offers strong optical stability for diverse applications. Whether used in optical auxiliary parts for high-definition displays or core optical components for automotive lighting, it maintains stable transmittance and refraction without parameter fluctuations due to environmental changes. Even for small transparent light-guiding parts of Bluetooth earphones, it ensures even light emission and enhances the product’s visual appeal. From the precision production of secondary optical lenses and light guide pillars, to the processing of optical components for automotive lighting, and the configuration of optical devices for high-definition displays, this optical silicone is highly adaptable. With its core advantages of high transmittance and excellent light guiding, it supports a wide range of optical devices and delivers outstanding light performance.
