A Must-Have Tool for Science Education

The Fresnel Diameter Acrylic Education Concentrator is a great investment for anyone interested in optics .Its design is perfect for science education. It can transform any plane wave into a spherical wave with adjustable concentric rings. The pros of this product include its affordability, ease of use, and durability. One potential con is that it may not be suitable for industrial and scientific use. Overall this concentric ring lens is an excellent choice for educational settings..

Pros
  • Lightweight and easy to handle
Cons
  • Requires careful handling to avoid damaging the delicate acrylic material

Not Worth The Money

This industrial and scientific product was a waste of my money. When i tried this product it DIDNT live up to its description.The instructions were unclear and made it difficult to assemble. The plastic used to construct the product was of poor quality. The only positive thing was that it shipped quickly. I do not recommend this product..

Pros
  • Shipped quickly
Cons
  • Poor quality, unclear instructions, waste of money
