Image Tube Grades
When buying night vision equipment you should be advised of
the different grades of image tubes. You should not buy a 2nd or 3rd
Generation night vision device without knowing the grade and resolution of
the Image Tube. The lower the Grade the lower the resolution or the greater
the blemishes.
Black spots are cosmetic blemishes in the image intensifier which do not affect the performance
or reliability of a night vision device. Some number of varying sizes is
inherent in the manufacturing process.
