Without lens Ronja goes only about 2 meters, see the Ronja testing procedure http://ronja.twibright.com/testing/ned_tetrapolis.php

With scale do you think improve this distance without lens? One could use multiple transmitters or a photodiode with a greater area. 
The architecture of the Ronja receiver allows arbitrarily high photodiode capacitance.
