Learn the capabilities and limitations of the Fresnel lens you select Fresnel lens performance will vary depending on the thickness and groove density in the lens. Higher-performance Fresnel lenses cost more money than lower-performance industrial Fresnel lenses. In certain instances a lower-performance Fresnel lens will work as well as a higher-performance lens.

I recommend:  Anchor Optics has Fresnel lenses for sale, and they explain how differences in groove density and thickness affect the quality of the Fresnel lens as well as its efficiency.

Buy from commercial Fresnel lens makers with good reputations Since a Fresnel lens trades a bit of image quality for lens efficiency make sure you choose a Fresnel lens supplier with quality Fresnel lenses for sale. It's easy to find a cheap Fresnel lens for sale, but take the time to compare two or three Fresnel lens manufacturers before making your final decision.
