Masers are amplified microwave emitting beam weapons. Though the microwaves are emitted over a wide area, the major concentration is a tight invisible beam. The maser beam cannot be seen unless a character is wearing a pair of IR high resolution goggles (not to be confused with normal IR goggles). Anyone wearing IR high-res goggles may be temporarily or permanently blinded if looking at the maser when it is fired at them.
Maser Penetrator: The maser penetrator is a handgun that is slightly larger than a rafflur M-2 pistol. It uses minipowerclips.
Maser weapons are commonly designed to use minipowerclips, though there is no particular reason for this; other models can accommodate full-sized powerclips or even active-matrix power sources like beltpacks or backpacks.
