3.1 Basic Set Up For Transmitted Light – Brightfield

1. First, set your interpupillary distance on the

microscope eyetubes by pulling them apart

or pushing them closer together to fit your

eyes. When set correctly, one will see one

uniform round field of view. Make note of

the distance setting when adjusted to your

liking so you can later repeat the setting.

2. Turn on the microscope power switch as

shown in Figure 1a marked number 10.

Adjust the brightness desired with the

variable brightness control knob shown as

number 8 in Figure 1a.

3. Make sure the aperture iris diaphragm lever

is all the way to the left (maximum opened)

to start. Refer to Figure 1B.

4. We recommend to initially us a specimen

that has areas of high and low contrast.

Place a specimen on the stage.

5. Select a lower power “scanning” objective

like the 4X or the 10X to find the area of interest on the specimen quickly. Be

sure the objective “clicks” into place when you turn the objective nosepiece.

6. By using the course and fine focus knobs shown in Figure 1a, adjust your

specimen into focus with your left eye closed (looking only through the right

eyetube). With the specimen in focus, close the right eye you just used and open

the left. If the specimen is out of focus for the left eye, adjust the diopter on the

eyetube until the focus in correct. The microscope is now adjusted for this user.

Focusing eyetubes allows us to compensate for users that wear corrective eye

lenses. If you wear glasses, you may want to remove the rubber eyeguards. Never

turn the left and right hand focus knobs in the opposite direction as damage to

the mechanism may result.

7. The aperture iris diaphragm located above the condenser and below the integrated

illuminator can be "stopped down" or closed somewhat to give the observation of

your specimen more contrast or resolving power. Stopping down the diaphragm

decreases resolution and brightness but increase image contrast and depth of

focus.
