4-2 Focusing Block

1. The coarse adjustment knob tension is preadjusted for easy use.

However, if desired, one can change the tension using the tension

adjustment ring @. Applying a large flat-bladed screwdriver to any of

the grooves ² on the circumference of the ring, turning the ring

clockwise (in the direction of the arrow) increases tension, and vice

versa.

2. The tension is too low if the stage drops by itself of focus is quickly lost

after adjustment with the fine adjustment knob ³. In this case, turn the

ring in the direction of the arrow to increase tension.

}This mechanism ensures that the objective does not come in contact

with the specimen and damage it.

1. After focusing on the specimen, turn the simplified pre-focusing dial @

on the focusing block so that the mechanism contacts the stage

holder.

2. To allow a certain margin for the focused position, return the simplified

pre-focusing dial by about a half turn from the position where the

mechanism contacts the stage holder.

#When it not required to use this mechanism, set the pre-focusing

dial @ to the uppermost position.
