Hello everyone, I am currently working on a project that involves a Fresnel lens. I needed a lens that could be adjusted easily.The following parameters can be changed- Focal length- Fresnel lens diameter- Thickness of the lens- The length of a groove (rib)- The amount of grooves- The spacing between groovesA tutorial on how to change the model has been included.The model can be changed by changing the variables used in the equations. After having done this edit the variable pattern feature by opening the table and dragging each column down like this.https://youtu.be/OCQlRw4Pcr4?t=3m23sI have included an excel file that shows what it should look like.Well, I hope everyone will get good use out of this model. Renderings of this lens are always welcome.
