FAQ

  • 1

    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.

  • 3

    Can you design the optical linear lenses?

    For now, we just do OEM designs. Our team is unable to do the product design.

  • 4

    What should I offer to custom silicone optical lens?

    Pls. offer us 3D drawing and performance requests.
