What are the points to consider when buying a Fresnel lens?

Fresnel lens is also called threaded lens, mostly made of polyolefin material, but also made of glass. One side of the lens surface is smooth, and the other side is engraved with concentric circles from small to large. Its texture is designed according to the requirements of light interference, interference, relative sensitivity and receiving angle. Let's take a look at what points should be considered when purchasing a Fresnel lens?

1. Pay attention to the workmanship of the product. The same thing is often damaged not because the quality of the internal parts is not up to standard, but because the external work is defective, and the surface is easily damaged, especially the Fresnel lens will not be dropped. Therefore, special attention should be paid to external work when selecting a Fresnel lens. There will be some differences in the material selection of Fresnel lenses, and you should purchase corresponding products according to your own use environment.

2. pay attention to the cost performance of Fresnel lenses. I believe many people will care about the price. Many manufacturers in the market sell Fresnel lenses, but the prices are uneven, so many users do not know how to choose. In fact, the price is not worth paying attention to. It should be noted that the Fresnel lens is cost-effective, the price is suitable, the product quality is qualified, the quality is good, and the price is cheap.

3. pay attention to the service quality of the manufacturer. If you want to buy a Fresnel lens from a manufacturer for a long time, you need to pay attention to the quality of the manufacturer's service. Because whether it is to collect money or follow-up after-sales service, it is necessary to deal with the manufacturer. If the service quality is poor, it will affect the integrity of the cooperation, especially the irresponsible after-sales service, which is easy to cause economic losses.

So today's explanation will come here first. The above is the whole content of today. I believe that everyone has a certain understanding of the points to consider when purchasing a Fresnel lens. Thank you very much for your patient reading.
