    • To protect the image intensifier, keep the lens cap on the objec- tive lens on when the device is not in use or when it is checked out in daylight conditions. • The IR illuminator produces a light that is invisible to a naked eye for use in conditions of extreme darkness.
  • Page 4 • Do not test the device in daylight conditions even with the day- light filter/lens cap on for more than ten (10) minutes. • To protect the device from damage do not direct it to the bright light sources (a fire, headlights of the automobile, lanterns, etc.).
  • Page 5 The level of equipment performance depends upon the level of light. • Night light reduces by passing through the clouds, while operat- ing under trees, at building shadows, etc. • The equipment is less effective when viewing into shadows and other darkened areas.

    SECTION III: OPERATION PRINCIPLES 1-8 MECHANICAL FuNCTIONS Mechanical adjustments of the PVS-7 allow for physical differences between individual operators using the system. The goggle’s func- tions include the power switch, interpupillary adjustment, release latch, eye relief adjustment, diopter adjustment, IR spot/flood focus (optional), compass illumination (optional), and objective lens fo- cus.

  • Page 20: Optical And Electrical Functions

    The optical functions include an objective lens, image intensifier, a collimator lens and two eyepieces. The objective lens collects light reflected from the night scene by the moon, stars or night sky and inverts the image and focuses that image on the image intensifier.
