Sunlight Writer

cults3d

A simple holder for a lens to focus sunlight and use as a sunlight writer. To use you need to be parallel to the sun with the holder and the object to be marked. Don't forget to wear sunglasses when using the focus is very bright. Burns leaves and cork mats almost instantly, dark items burn quicker than lighter items. This was created to use Double-Convex (Bi-Convex) Spherical Lens, 50 mm Diameter, 50 mm Focal Length. http://www.amazon.com/gp/product/B00EPQ9SO4?psc=1&redirect=true&ref_=oh_aui_detailpage_o09_s00 The above are out of stock, I think these will work as well but I have not tried. http://www.amazon.com/SEOH-Glass-Double-Convex-Length/dp/B0088AQZ08/ref=sr_1_5?ie=UTF8&qid=1455483635&sr=8-5&keywords=double+convex+50mm+lens The lens should have a drop or two of glue to hold it in snugly.
