Precision Molded Plastic Lenses
We manufacture plastic lenses for a wide range of applications such as magnifiers,
low vision devices, receiver-emitters, condensers, mirrors, imaging systems etc.
We also design & fabricate custom made OEM plastic optical elements to suit
specific applications. Main advantages of plastic optics lie in low per piece cost;
integral molding of mounting fixtures (making assembly simpler & more economical);
easy & highly economical production of aspheric surfaces and other complex forms;
light weight and break-resistance.
We routinely supply plastic optical lenses to the following specifications:
