Hartridge spectrometer with optical cable at input
Today I was working on a setup that could be OK for taking stellar spectra with telescope.
Hartridge spectrometer is coupled to light source with optical cable.
To minimize the light losses, I used old eyepiece from broken theodolite to obtain parallel beam ~ø6mm, which was then directed to slit via cylindrical lens (it is part of spectrometer).
Now I am working on bracket that will keep the fiber in focal point of my C11.
