Centering the Condenser

1) Bring the objective 10X into the light path.

If a specimen is placed on the circular rotat-

able stage without a mechanical stage it is

recommended t o hold the peripheries of the

specimen with the stage clips provided.

2) Swing in the condenser top lens, and bring

the specimen into focus.

3 ) Stop down the field iris diaphragm

Remove the specimen out of the light path

that a transparent area comes into the

light path. Keeping the polarizer at the

"0"

position, rotate the polarizer rotation ring

until the optimum extinction is obtained,

then clamp the ring. (Fig. 12)
