Spectrometers
Someday I would like to try to build one.
These are some notes that may be helpful when that day comes.

The OPL
In early January 2020, a bunch of my buddies became enthused about using a spectroscope to
analyze the fluorescence from Uranium minerals.
OPL is a company in England. They say that both the "pocket" and "teaching" model use a 600 line per mm grating.
The pocket model is 55mm long, 12.5mm wide.
The teaching model is 104mm long, 25mm wide.
My buddies are using the teaching model of the OPL.
The following writeup is by Paul Adams who pioneered all this.
The "ImageJ" software package takes the spectrum out of the image file.
Optics factory claims, "It is the same spectroscope that JTV.COM sells for $99".
