Laser Diffraction Grating
thingiverse
Experience wave/particle duality with this affordable laser diffraction grating. Compatible with regular laser pointers, it enables double-slit experiment demonstrations. Learn more at http://en.wikipedia.org/wiki/Double-slit_experiment. Choose between DiffGrating50 and DiffGrating25 STL files; the former is easier to print but less effective. Set layer height to .25mm, extrusion width at 0.4mm, and ensure your slicer doesn't create a wider first-layer extrusion for optimal slit formation.
With this file you will be able to print Laser Diffraction Grating with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Laser Diffraction Grating.
