Hi, i tried similar collimating lens from a Raman spectrometer (the focussing sleeve for the probe) and it sure does increase the IR to about 50m. But as it is a highly focused light, hitting the IR apple 50 m away is a challenge-did have to fire more than 10 shots to hit the TBU.
mine lens was from a Renishaw Raman spectro, and does look like this:

It has 5.5 mm inner diameter enougn yo fit the IR bulb, let me get a video of it in action soon...
This way, firepower can be modelled! But an fpv tank might b needed to fire more accurately
