Simple semiconductor sample holder

pinshape

Summary A simple sample holder for semiconductor wafers is designed for optical experiments. This component is part of the Open-source optics project, which aims to drastically cut the cost of scientific optical hardware. The Michigan Tech's Open Sustainability Technology Research Group is behind this effort. For similar projects, check out "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. Use the OpenSCAD files to customize it for your application. Print it on your favorite open source 3-D printer, and you're ready to go. The two components are held together by M3 screws. You'll need a thumb screw from Thingiverse (30500) to complete the project. If you need the base component, head over to Thingiverse (28133).

This sample holder 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's all part of a larger effort to reduce the cost of scientific equipment using open-source hardware. For more information on this project, read on.
