Review: Lens X six - I was excited about receiving the lenses . The lenses are high quality and I would recommend this to anyone . To microscopic to telephoto lens . It'll keep me busy . You can't find the selection when you come to a store . They are useful , since I am going to build a telephoto lens for my camera . And they are inexpensive also . I saw the same lenses at other sites twice the price . I am really satisfied with this purchase .
Review: A great educational tool - I bought these lenses for a science lesson on optics. They were perfect. I was able to use two of them to make a simple telescope using a cardboard tube. The students were completely fascinated by their shape.

## Questions & Answers

**Q: If a person places 2 of these lenses a few inches away from each other in a tube, will it work like a monoscope?**
A: A monoscope was a kind of tv pattern generator used to tune a tv system 30 years ago,  so they don't.  If you mean a telescope,  you could place two of this lenses in a tube about 28 inch apart,  with a magnification of about 2.5,  so it just work as a demo,  not a practical telescope.

**Q: are they labeled, like which one is concave and which one is convex?**
A: They are not labeled, but the convex lenses are thicker in the center, with thinner edges. The concave lenses have thinner centers and thicker edges.

**Q: Could I use these to magnify the image from a cheap movie projector?**
A: Has not been tested for that application, feel free to give it a shot though; if optical lenses do that, then these are optical lenses.

**Q: Would these work to make a simple refracting telescope??**
A: In theory yes, but please be careful in reviewing focal length ratios to ensure that the tube length is reasonable.
