BASE & CROSS CURVE MEASUREMENT

[Husseinali Datoo]

Can anyone help me:
How can I measure BASE & CROSS CURVE after the lens has been generated?
This is to know if the lens has been generated according to diptre power.

I have the manual Mitutoyo sagometer.

Anyone has such instrument

e mail me privately at

Thanks.

Align the pins of the sagometer with the pins on the back of the button. Read the curve. Rotate lens 90 degrees and do the same. Lowest curve = base, highest curve = cyl.....
