What I want to do
A DIY low cost high performance Raman spectrometer.
My attempt and results
After about two years of trials finally succeded. A detailed paper entitled: "A Homemade Cost Effective Raman Spectrometer with High Performance" has been just published in the open access "Journal of Laboratory Chemical Education", available at: http://www.sapub.org/Journal/articles.aspx?journalid=1139.
I hope it has useful information for some of you. After the trials, a device can be made in short time. The picture shows an example of the obtained Raman spectrum for benzene and an internal view of the device.
Questions and next steps
Please do not hesitate in contact to me for further discussions.
Why I'm interested
It could be a long story. In brief, when student (very long time ago) i was very frustrated because the laboratory had an old fashioned Beckman DB spectrometer in bad condition and for wished to make my own spectrometer. my first one (using a piece od DVD, a webcam a cheap fiber optic patch cord and slit made with pieces of razor blade) worked good by 2009. Few years later I found this nice Group and tried few small contributions.
As a chemist I am very intersted in optical spectroscopy and particularly in what I call "Alternative Scientific Instrumentation" which denotes high performance instrumentation made at low cost because it relies on the use of components of high technology with a worldwide availability and massive consumer market.
