Focusing the Specimen (fig. 15)
1. Focus the specimen with 10x objective. To avoid the objective touching the specimen during focus-
ing, you should raise the mechanical stage to let the specimen close to the objective at first, then
slowly separate them to bring the specimen to focus.
Turn the coarse focus knob 1 conversely to lower the specimen and search images in the 10×ocular
simultaneously, and then use the fine knob 2 to focus. After that, you can replace with other magnifi-
cation objectives safely, and focus without the risk of damaging the specimen.
• To make the observation more convenient, you can use the locking set 3 to fix the stage in a vertical
direction.
