While its intended design is for deep space construction, the concentrated laser beam of the Spectra is highly effective against organic and synthetic enemies.
The Spectra is a Corpus pistol unlockable through Energy Lab Research in the dojo. Released in Update 9, it appears to be a handheld cutting laser that (according to its description) is as effective at cutting flesh as it is at cutting metal. It is essentially a sidearm version of the Flux Rifle, with the focus on Puncture
instead of Slash
The Spectra's beam has a maximum length of 15 meters (compared to the Flux Rifle's 25 meters) and approximately five seconds of firing time before the cell runs dry.
Very useful with Volt as his Electric Shield can give the spectra infinite range, with added electrical damage.
Similar building with the Flux Rifle, adding Magnum Force to the Spectra can actually be beneficial, as the shooter does not require precise aiming. This will further reduce its medium range effectiveness however.
The Spectra is essentially a smaller Flux Rifle -- dealing as much damage as the Flux Rifle did on release, albeit with shorter range and reduced ammo capacity.
It specializes in puncture damage, which makes it better then the Flux Rifle against the Grineer.
Spectra is the plural form of spectrum, which essentially means "range".
Ironically, range is something this weapon lacks.
During the final phases of the Arid Fear event, the corpus scouts were equipped with Spectras, which they would use for short durations before attempting to run.
Ceasing fire from the Spectra actually retracts the beam.
