Advantages of Plastic Optics

Molded plastic optics offer numerous advantages over other optical materials, making them a preferred choice for various applications.



One significant advantage of molded plastic optics is their lower cost compared to traditional optical materials like glass. This cost advantage is particularly appealing for mass-produced optical products.


Lightweight Design

The density of optical plastic is only 1/2-1/3 of that of glass, so molded plastic optics are inherently lighter in weight, making them ideal for applications that require a lightweight design.


Flexible Processing

plastic injection molding can achieve complex geometries and details, such as aspheric surfaces, microlens arrays, Fresnel lenses, etc. making it possible to integrate other functions on optical components.


Quality consistency

All plastic optical lenses are pressed with the same mold core, as long as reasonable and stable process parameters are adopted, the surface shape of optical plastic parts will have very good consistency.



Some plastic materials have excellent impact and corrosion resistance, making them ideal for optical applications in some special environments, such as outdoor optical equipment.


Efficient manufacturing

The optical surface and the positioning surface of plastic optics can be extruded at the same time.
