Free Other STL Download - Physics Diffraction Slide Holder and Laser Pen Holderby Fred Houweling

This is a slide stand and a laser pen holder to allow students and teachers to conduct/demonstrate the double slit experiment with different wavelength laser lights. The slide holder doubles as a storage holder for your slides. The laser pen holder suits a common laser pen sold online in sets of 3 different wavelengths. This was originally designed to help a student conduct their extended experimental investigation.
