Product Information

Silicon convex lens is a lens with thin edge and thick middle. At least one surface must be made into a sphere, or both sides can be made into a sphere, it can be divided into biconvex lens, planoconvex lens and concave convex lens. LSR convex lens is a kind of refraction imaging, which converges light. Made of highly transparent liquid silicone, it's anti-yellowing and UV resistance, the material of aspheric optical lenses is Dow Corning MS1002, hardness is 72 Shore A. Ultra Transparent LSR lenses light transparency is from 91% to 94%. The temperature that optical silicone lenses can withstand is from -40 ℃ to 200 ℃. 

While optical silicone concave lens, also known as negative spherical lens, has thick edges and thin middle. At least one surface of the aspheric silicone concave lens shall be made into a spherical surface, or both sides shall be made into a spherical surface. It can be divided into biconcave lens, flat concave lens and convex concave lens. Silica gel concave lens is a kind of refractive imaging, which can diverge light.

    What’s the advantage to choose liquid silicone to make optical lenses?

    Comparing to Plastic, the properties of light transmittance, anti-yellowing and weathering resistance are better. Comparing to Glass, the optical liquid silicone is easy to shape, the fluidity makes the complex or micro-structure designs moldable.

  • 2

    What’s the level of your clean production workshop?

    Currently, for Liquid Injection Molding, the workshop is Class 100,000, while for plastic, our factory has Class 10,000, or even Class 1,000 clean workshops.
