Does the Laser Module make the lens calibration for the Focus Module unnecessary?

No, the Laser Module only tells the Focus Module the accurate distance to a target.

But if the Focus Module was not calibrated properly, meaning that the Focus Module was not told at what distance the target is in focus, then the target will not focus even with the distance being accurate.
