Spectrometer#

Spectrometers measure the distribution of light (or other waves) across wavelengths. Their behavior is stable, predictable, and grounded in well‑characterized optical and electronic principles.

Dimensional Core (SET)#

• Spin: not relevant
• Elec: detector response, signal processing
• Temp: affects detector noise and optical alignment

Why Green‑Zone#

Spectrometers operate in a clean, coherent optical regime.
Their measurement principle is direct: dispersion or interference mapped to wavelength. Calibration is stable, drift is predictable, and environmental sensitivity is well understood.

Regime Notes#

• pos‑regime: stable illumination, controlled optics
• Q‑regime: thermal drift, detector noise, minor alignment shifts
• neg‑regime: vibration, unstable sources, coherence loss

Alignment Notes#

Already aligned.
Explicit notes on thermal stability and optical alignment improve precision but require no conceptual changes.
