3 Coarse focusing

8.3 Focusing

There is a focus wheel on the left side of the

stand for coarse and fine focus adjustment

(Fig. 59b).

On the right side of the stand, there is also a fo-

cus wheel, which is used exclusively for fine fo-

cusing (58.4).

The special form of this handwheel makes it

possible to simultaneously grasp the coaxial

drive with your hand while operating the fine

adjustment with one finger.
