In this video I show how to produce 3D printed optical lenses in relatively good quality. I have designed and built a 3D printed lens grinding and polishing machine. With this machine it is possible to grind and polish 3D printed optical lenses precisely. I show some experiments to find out the focal point. I measure the transparency of the lenses with an Arduino and a photoresistor and build a simple magnifying glass. With the lenses it is possible to build simple telescopes, magnifying glasses or many other optical devices.
I show all experiments and exact details about the production of optical lenses on my website: fraensengineering.com/how-to-...
If you would like to carry out optical experiments yourself, you can download the files here: www.etsy.com/at/listing/16071...
