## 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.
