Can You Calculate Radiance from Irradiance Outputs Using a Spectroradiometer?

Hi,

When you measure irradiance using a spectroradiometer, can you calculate radiance based on the irradiance outputs? How does one measure the angle in cosθ and solid angle Ω in the radiance formula?

Thanks!

No , I don't think so...

Yes , you can. Just google it... There is a very wide explanation over there.
