A Focusing Lens is an upgrade that boosts the throughput (speed) of Laser Energy Transmitters.
Lenses are crafted out of either mob drops or crystals found deep underground. Some lenses provide a linear/flat boost to the PPS, while others provide a percentage improvement.
Strategy[]
In the early game with Basic, Mk 1 and Mk 2 Laser Energy Transmitters, it is recommended to use the flat-boost lenses (Diamond, Emerald, Ruby & Sapphire) as it will give you a better boost. e.g. A Mk 2 Laser with a Sugalite (+200%) lens provides less boost than a Sapphire (+100 PPS)
Once you have Mk 3 Lasers, it is recommend to switch to a percentage-boost lens as most will provide a better boost than the best flat-boost lens (Sapphire).
