A circuit board is provided on a calorimeter plate with obverse and reverse sides for measuring irradiance from a laser that strikes the obverse side via temperature response from the reverse side. The board includes an electrically insulated substrate and an electrically conductive trace. The substrate has first and second surfaces. The substrate mounts to the reverse side along the first surface. The electrically conductive trace is disposed onto the second surface of the substrate.
