VIAOPTIC manufactures high-precision polymer optics tailored to your needs: spherical, aspherical & freeform lenses, Fresnel & cylindrical lenses, lens arrays, prisms, mirrors, micro- & diffractive structures. PMMA, also known as acrylic or under trade names like PLEXIGLAS®, is one of the most commonly used materials in optics. It offers high light transmission (up to 92%), excellent UV stability, and is cost-effective to process. The refractive index of PMMA is approximately 1. Advantages:. There are various highly transparent organic polymer materials which can be used as optical materials for a range of applications. Search a comprehensive database of resources, including technical papers, best practices, tips, FAQs, and more. Why is high refractive index important? Why is high. Expertly crafted high-precision polymer optical solutions, from individual components to fully assembled opto-electronics: all under one roof. Aspherical lenses are not more.
