Here is something attained off from this old instrument a flame atomic absorption spectrometer, which was decommissioned after total failure, it was used up, the one in the picture. Anyway out of the abyss came this most perfect triangular prism. It is as fine a piece of glass as any microscope or telescope optic out there. Given the price of the instrument in 2007 this is one pricy piece of glass well over a thousand dollars. High end instrumentation from PerkinElmer, what do you think. Notice it has vertical transparent quality yet its internal facets are as reflective as any primary mirror going. With one angle of the facet looking like as pure a dark abyss of which you could reach out across space with no end on the other side. Transparency yet full reflectivity, what this prism did was to bend the light at many different bandwidths in the nanometer range outside of the visible spectrum associated with the frequency of different elements and cast that light toward an array of mirrors that collimated the beams aimed at the highest stable average energy levels to be picked up by a detector. And oh does it ever spread the visible spectrum out. I cant wait to use it on the Sun spreading the spectrum out which I hope to get a picture of. I know how to make a splitter out of cardboard so as to display the solar spectrum on a screen within a darkened box. But I have never seen a prism this big and heavy used in one, the problem is holding it fast enough as to held nicely in place without interfering with its optical properties.
