6 Design Considerations for Polymer Optics

Quality. Quantity. Cost. In precision manufacturing, the consensus is that you can improve two out of three. You can’t get “more stuff that works better but costs less.”

Molding Hybrid Diffractive IR & Plastic Lenses: More Power, Less Glass

A hybrid diffractive lens is a refractive optical element with a custom-designed diffraction profile encoded onto one surface. Such a hybrid literally combines the power of refraction and diffraction; as such, a single hybrid lens can replace two or more refractive lenses, especially when utilizing aspheric surfaces. Furthermore, because diffractive surfaces have “negative optical dispersion,” a hybrid lens can make an excellent single-element achromat(*). This technique of combining multiple lenses into single hybrid lenses enables optical designers to reduce the overall mass, volume, and material cost of an optical system.
