END-TO-END ELEMENTAL GAS CALIBRATION · EVERY UNIT
Atoms are predictable. An excited gas emits light only at its quantized transition wavelengths — nature's own ruler, reliable everywhere. Every Aura Hacker spectrometer is calibrated end-to-end against those emission lines — like a good little USA-built spectrometer should be — and ships with its own factory calibration file on the drive. Most instruments at this price ship uncalibrated. Ours do not.
These are the actual emission lines professionals look for. Pick a gas: the background lights up with its real spectrum, and every plot on this site — including the front page's sensor — switches to it. Sweep the monochromator across a line and it flashes.
A spectrometer maps sensor pixels to wavelengths. That mapping is only as honest as its reference points. We excite elemental gas discharge tubes with high-voltage — argon, hydrogen, mercury, neon, and more — record where their known lines land on the sensor, and fit each device's optics' true curvature stack-up to a linear sensor. The result on our bench: sub-nanometer typical accuracy (slit-dependent) across the range, verified per-gas with ±nm reporting you can re-run yourself in the software.
