Irradiance and radiance

  1. Sep 28, 2012 #1
    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.
