Science Education Double Concave Glass Length SEOH Review

As a result of my tests, I determined that this double concave lens is perfect for science education. It is made of high-quality glass, which provides clear and precise images. The lens is easy to handle and can be used for various experiments. However, it may be somewhat expensive compared to other similar products on the market. Overall, I highly recommend this product to anyone who wants to enhance their science study with quality optics.

My daughter used this for a telescope science fair project. I can't comment on the quality of the lens, but for the project it served its purpose for focal lengths and building small telescopes.

The lens got dirty and after cleaning I noticed tiny indentations in the lens. The lens was too imperfect for my use, but it met the written/printed specs and had a decent local (i.e. state) delivery rate. I don't like complaining about small purchases, but I can't say I'm happy with this purchase. PS I didn't expect quick delivery even though I live in Houston; However, what I didn't expect was that the package came from Navasato, Texas.
