The 3D Printed Open Source Spectrometer

[Brian_Krassenstein]

A key piece of laboratory equipment is a spectrometer which, while useful, can be prohibitively expensive. When Ben Hickman, of the University of Hawai’i’s Oceanography department in the School of Ocean and Earth Science and Technology (SOEST), sought to develop a more "democratized" version of the device, he turned to 3D printing. Brian Chee, an IT specialist at SOEST, came to the rescue to bring optics and 3D printing together to create a working spectrometer. The goal was to produce a spectrometer in the range of about $100 -- rather than the common thousands to hundreds of thousands of dollars for traditional spectrometers -- the device can now be accessible not only to large-scale laboratories, but also to individual students who no longer need to queue for a shared device. For more details on the device, process, and future projects, check out the full article: http://3dprint.com/54768/open-source-spectrometer/

That looks really nice. DO you have any sample spectra? I wonder how it compares with publiclab's spectrometers.

Also, could you post the total list of parts (preferably with suppliers) and the .stl file?

I would very much like to try and construct a prototype ...
However, I have not been able to find detailed files for printing the various 3D parts and also details of gratings and optics used ...
Are these available please ?
