Simple semiconductor sample holder v3

Prints (0)


Summary This is an improved simple sample holder for peices of semiconductor wafers for optical experiments. This component is part of the Open-source optics project, whose goal is to radically reduce the cost of scientific optical hardware: by the [Michigan Tech's Open Sustainability Technology Research Group]( For similar 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. This is an improvement on the last version - as now you can change samples easily using tweezers and one hand only. It uses less plastic than v2 and has a cutout for samples that are short. Print on your favorite open source 3-D printer and enjoy. You can hold it to the smooth rod using m3s and the thumbscrew. Use the thumb screw from If you need the base go to Full information here Thanks 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. This is part of a larger project to reduce the cost of scientific equipment using open-source hardware. Read more here
