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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by M***E on March 17, 2026* Quick shipping, good product ### ⭐⭐⭐⭐⭐ Sturdy and safe *by L***N on May 29, 2025* Great lenses for straightforward, simple optics experiments.
