-Dimensional tolerance
Difference between the mean and the basic diameter of the maximum and minimum values of the diameter measured by changing the direction of one ball lens


-Sphericity
The maximum radius distance between the ball lens surface and the minimum spherical and ball lens points

-Variation
Variation in Lots The difference between the average diameter of the maximum ball lens in a lot and the average diameter of the minimum ball lens
