Simple semiconductor sample holder v3

pinshape

Summary This is an enhanced simple sample holder for pieces of semiconductor wafers designed for optical experiments. The component is part of the Open-source Optics Project, which aims to dramatically lower the cost of scientific optical hardware by radically reducing costs: through the Michigan Tech's Open Sustainability Technology Research Group. For similar information see the Open-Source Lab How to Build Your Own Hardware and Reduce Research Costs Instructions This open-source sample holder is designed to hold a semiconductor wafer part on a smooth 8mm diameter rod. It is an improvement over the last version - now you can easily change samples using tweezers with one hand only. It uses less plastic than v2 and has a cutout for short samples. Print on your favorite open source 3-D printer and enjoy it. You can hold it to the smooth rod using m3s and the thumbscrew. Use the thumb screw from http://www.thingiverse.com/thing:30500 If you need the base go to http://www.thingiverse.com/thing:28133 Full information is available here Thanks are due to Chenlong for designs on 3D Studio Max. This component is part of the Open-source Optics Library: Zhang C, Anzalone NC, Faria RP, Pearce JM (2013) Open-Source 3D-Printable Optics Equipment. PLoS ONE 8(3): e59840. It is a part of a larger project to reduce the cost of scientific equipment using open-source hardware. Read more here
