Find Fresnel lens manufacturers and info on Fresnel lenses online
By Cathy Salustri Commercial Fresnel lenses range from the size of an eyeglass lens to the size of a lighthouse lens. Finding an industrial Fresnel lens manufacturer that suits your needs means looking at information about Fresnel lenses online and knowing what you're looking for in that information. Gather information about Fresnel lenses and then make your decision.

Fresnel lenses have a multitude of applications, so research the specifications on the commercial Fresnel lenses you need as well as the Fresnel lens suppliers who will provide them. These three starter questions will get you headed in the right direction.

1. What specification of Fresnel lens fits your need?

2. What are the capabilities and limitations of the Fresnel lens you select?

3. Where can you buy Fresnel lenses from commercial Fresnel lens manufacturers with good reputations?

Find the type of Fresnel lens you need

This is the easiest step: ask yourself where your company will install the Fresnel lens. The application will guide you in your search for info on Fresnel lenses online.
Try:  Fresnel Technologies lists a basic rundown of what types of industrial Fresnel lenses get used in different applications. For more detailed applications refer to Reflexite Display Optics' white papers on Fresnel lenses.

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.
Try:  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. Champion Technology lists Fresnel lenses for sale alongside their specifications and any remarks about their performance or advantages.

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.
Try:  Edmund Optics has more than 65 years of experience dealing with optics like Fresnel lenses. But if you want a worldwide selection of Fresnel lens suppliers, Alibaba.com allows customers to look at a myriad of different industrial Fresnel lens manufacturers around the globe.

• When replacing a commercial Fresnel lens, save time by looking through old purchase records to find the name of the Fresnel lens supplier that sold the lens you want to replace. As long as the Fresnel lens performed well, there's no reason to reinvent the wheel.
