table include a tolerance.)
a’(N) = {(SS × 18.56/0.6299) + 3.3} × 1.03
a’(M) = {(SS × 22.61/0.6299) +3.3} × 0.97
x = b + (SS/0.6299 × 3.2 + 57.0)
The installation measurements and their calculation method for each lens are shown above.
The alphabetical letters in the charts and calculation methods indicate the following.
