Nano-Pulse Plasma Stream Lenses

A Plasma Lens Cobbled together by a Jedi Padawan, this is the default component of a Nano-pulse weapon.

A Beam Gem lens was a type of lightsaber focusing lens that was manufactured primarily from beam gem crystals. 

These crystals commonly found use in optical computers, for example within navigation computers and, 

when used as a lightsaber lens, produced a highly focused blade.

The vibration lens was a type of focusing lens used in the construction or upgrading of lightsabers. 

As its name suggested, the lens vibrated at a high rate of speed. This enabled the weapon to produce a more deadly, if less stable, beam.

The kunda stone has numerous practical applications in medicine and communications. 

It can also be combined with normal lens to produce a broader, yet still focused beam. 

An Ossus dueling lens was a type of lightsaber focusing lens that was widely used at the Ossus Jedi Enclave. 

It was intended to create a highly focused blade for providing fine-tuned control over one's lightsaber.

A Byrothsis lens was a lightsaber focusing lens created using Byrothsis, a compound that was originally used to create infrared camera lenses. The resulting focusing lens was capable of strengthening the lightsaber beam, although the wielder of the blade had a more difficult time deflecting enemy Energy bolts.
