Abstract : The Night Vision Sight, Crew Served Weapons, AN/TVS-5, is a passive image intensification system which uses the low-light-level illumination of the night sky (i.e., starlight, moonlight) reflected from the object and its background to form an erect, clearly defined image. The primary components of the sight are the objective lens assembly, image intensifier tube, tube housing, and the eyepiece assembly. The objective lens assembly's primary function is to focus the light image on the photomissive cathode of the image intensifier tube. It also contains the reticle and its adjustment mechanism used in zeroing the sight to the weapon. The image intensifier tube amplifies the low-light level image and presents a highly intensified image on a phosphor screen. The eyepiece assembly magnifies the resultant image and presents it to the human eye. The eyepiece assembly also contains the necessary adjustments for focusing the sight at various ranges and for making the proper diopter adjustments for correcting the sight picture for the individual variances in the human eyes of the various users. The tube housing contains the wiring and housing for the battery-operated power supply. With the exception of the objective lens assembly, all components of the AN/TVS-5 are identical to the components of the Night Vision Sight, Individual Served Weapons, AN/PVS-4.
