Where to Buy Plastic Optics

Knight Optical offers a variety of plastic optics within our stock catalogue including spherical lenses, aspheric lenses, Fresnel lenses, windows, diffusers, filters, and waveplates. We can also provide custom plastic optics, such as optical domes, and due to the moulding process, we can also produce more complex shapes. Enquire for further information.

Shanghai Optics produces the highest quality plastic optics in a variety of shapes, including aspheric lenses, optical prisms, cylinder lenses, toroid lenses, and free form optics. Our state of the art in house equipment allows us to use the most efficient ways to produce polymer optical components, including single point diamond turning and machining, CNC machining, and injection molding.

Injection molding is the most common way to manufacture large quantities of polymer optics. During the molding process melted thermoplastics are injected into prepared optical forms. Shanghai Optics has extensive experience in optics molding and especially in developing high quality molds for both standard and custom optics. Our optical design team has experience preparing both single cavity and multi-cavity molds, and molding acrylic (PMMA) lenses, polycarbonate lenses, cyclic olefin polymer lenses, etc.
