OK! Sorry for the mix up. To simulate free space effects on the spatial profile use the Spatial Connector component, which is found in the “Default/Passives Library/Optical/Connectors” folder. I’m going to guess you were using the FSO Channel or the OWC Channel to simulate your design and it wasn’t giving the results you were looking for. The reason being is these components include transmitting and receiving telescopes in their models and so the spatial profile is not changed.
