|fig. 3 Spectrometer I am Putting Together|
I am trying to build a spectrometer. The first figure you see of the spectrometer that was purchased from Public Lab by friend that he has let me use. It works well uses a DVD for a diffraction grading. The biggest concern with this product is the camera inside is always coming loose (fig 2) and there is no place to put the sample that you are testing. Need to make a sample holder.
In the third figure (fig 3) you see I am using many of the holders from my optical bench except I picked up a magnetic white board to hold these holders. It is larger and being white I can see measurements on the red ruler much easier.
I 3D printed a slit and a sample(cuvette) holder and used my own diffraction grading that I purchased from Amazon. For the camera I am trying a PS3 camera that I found for $3. For the software I am using Theremino spectrometer. There website has plenty of information about spectrometers.
I will be continuing the spectrometer build using different web cams and enclosures. I will keep posting as I build it.
