## spectral responsivity

https://doi.org/10.1351/goldbook.S05829
The spectral output quantity of a system such as a photomultiplier, diode array, @I02944@ device, or biological unit divided by the @S05817@ $$s(\lambda) = \frac{\text{d}y\left(\lambda \right)}{\text{d}E\left(\lambda \right)}$$, simplified expression: $$s(\lambda) = \frac{Y_{\lambda }}{E_{\lambda }}$$, where $$Y_{\lambda }$$ is the magnitude of the output signal for @I03255@ at @W06659@ $$\lambda$$ and $$E_{\lambda }$$ is the @S05817@ of the parallel and perpendicular incident beam at the same @W06659@.
