The night vision system supports the replacement of different magnification lenses to meet the requirements of different observation distances. When replacing the objective lens, the objective lens is rotated counterclockwise. Remove the object lens mounted on the night vision instrument. Then the objective lens that needs to be replaced is rotated clockwise to be installed on the host of the night vision instrument.
