    Lens for making Telescopes

  • We used this lens along with the 500mm lens to make a telescope http://www.hometrainingtools.com/a/telescope-optical-science-project. The lenses came undamaged and worked great for the project. The lenses were a great price (cheaper than Amazon) and the shipping was much faster than I expected.
    Great for making telescopes!

  • These were used to make telescopes in our preschool camp. The kids loved them and were very excited to learn how the lenses worked. I appreciated that they were individually wrapped although it would be nice if they were all labeled individually. About a third of them were unlabeled. The price was great too.

  • I am teaching a space summer camp and the kids really enjoyed making refracting telescopes a la Galileo. They were way impressed that the lens were real glass.
