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 damage.
The Spectra's beam has a maximum length of 15 meters (compared to the Flux Rifle's 25 meters) and approximately sixteen seconds of firing time before the cell runs dry.
Holding down the fire button while using Shade or a Huras Kubrow will cloak you if enemies are nearby, letting you potentially deal large amounts of damage without retaliation.
The Spectra is essentially an alternative to the Flux Rifle to due to being a beam-based weapon, although it loses versatility by its shorter range, non-instantaneous beam, making it effective only at mid-short ranges.
It specializes in puncture damage, which makes it better than the Flux Rifle against the Grineer.
The Spectra has the unique capability of cutting corpses into pieces, similar to Slash-focused melee weapons. This makes the Spectra the prime candidate for a DesecratingNekros to bring along, as the game considers the cut corpses as separate entities, essentially giving multiple corpses to desecrate from a single enemy and thus yielding more chances to create more drops.
Alternatively, Spectra can be used to assist Desecrating Nekros to yield more loots.
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 currently known to be one of the most improved weapons throughout the game's patches, as it was one of the weakest Clan DojoResearch weaponry ever released: It used to deal a total of 8 damage per second.
