This will add a beam from infinity to the system. The beam will pass through the cardinal points. This type of light source will not work if the system is afocal. Object beam angle Object beam width

This will add a beam from infinity to the system. The beam will pass through the system but not through the cardinal points. This type of light source will work if the system is afocal/focal. If the outgoing rays are detected as collimated - the exit angle will be reported. Object beam angle Object beam width
