The absolute spectral resolution of the payload is given by:

$$ \Delta\lambda = \max\left( \Delta\lambda_{\text{sensor}},\Delta\lambda_{\text{optic}} \right) $$

Where

• $\Delta\lambda_{\text{sensor}}$ [m]: Sensor-Limited Spectral Resolution
• $\Delta\lambda_{\text{optic}}$ [m]: Optically-Limited Spectral Resolution

Assumptions

• No abberations.
