When I add a Thorlabs lens from the catalog in Non-Sequential Mode, two entries are added in the Non-Sequential Component Editor. The first is a Null Object , and the Comment contains the name of the lens followed by '.V'. The second is a Standard Lens, and the Comment is the lens name followed by '.1'. It has all the expected lens properties, and its Ref Object is set to the Null Object that accompanies it.

Is there some utility here? Is it better to position the Null Object and let the lens follow it or something? Thanks.
