(a) Ambient Operating Temperature 10°C to 35°C (Non-Condensing)

(b) Measured Argon Peaks Within the Detection Range

(c) Calculated Value: Bandwidth Over Amount of Pixels

(d) If the entire wavelength detection range is used.

(e) Quantified using a bandpass filter with an optical density of 4 in the blocking region. The stray light is calculated by comparing the light detected at wavelengths in the filter's blocking regions to the light detected without the filter in place.

(f) If the fiber patch cable is switched or replaced, the spectrometer will need to be recalibrated.
