Ukemark's alchemy team was insanely efficient, to say the least.
They'd finished making five full sets of Jia Xiu's super-imprecise spectrometer and had them delivered within a week.
He'd commissioned the alchemy team because Ram wasn't very good at making instruments that required such precision, and glass was his blind spot. The convex lenses they'd used before had all been made by Jia Xiu, who'd melted glass rods himself.
As for why there were five sets, it was because his design was imprecise, so the alchemists had added their own interpretations and refined it. Since they weren't sure what exact effect Jia Xiu wanted, they'd made five versions with different details.
Jia Xiu wasn't the only one studying light here. Some scholars and spellcasters had conducted research as well, and had already discovered the phenomenon of light dispersion.
The biggest difference between Jia Xiu's needs and those previous studies was that he wanted to replace the pinhole with a slit.
In theory, that should improve precision, but Jia Xiu wasn't entirely sure. He'd never studied optics; he'd only come across the spectrometer in a popular science story.
In the laboratory that belonged to Jia Xiu at Aurelius's Mage Tower.
Thick curtains covered every window in the lab, leaving only a small patch uncovered to let in sunlight.
The sunlight that streamed in reflected off several plane mirrors before falling precisely on the slit of the spectrometer's collimator.
It took Jia Xiu nearly two hours to get it aligned.
He'd also had Ram cast Guidance on the spectrometer beforehand. He had no idea if it'd help, but there was no harm in trying.
The incident light passed through the compound lens in the collimator, then refracted through the Dispersion Prism. The different frequencies separated because they had different refractive indices, and
