5. Now, switch to an objective with a higher

magniﬁcation level (no oil objective) and

bring the specimen into focus while looking

through the eyepieces with both eyes.



The depth of ﬁeld is lower for higher

magniﬁcation levels. Thus, you will

notice that if you switch to low magniﬁcation

after bringing the microscope into focus with

great magniﬁcation, a minor adjustment of the

ﬁne focus may be required.



If you are comfortable wearing your

corrective lenses (contact lenses or

eyeglasses) for microscope viewing, leave them

on and your adjustments will be minimal.

2. Bring the specimen into focus using 10x

magniﬁcation and the ﬁne adjustment

knob while looking through only the right

eyepiece. To help focus, cover or close your

left eye.

3. Now look with your left eye through the left

eyepiece (focusing eyepiece). Now focus

using the focus function of the eyetube.



When doing so, do not change the

height of the specimen stage.

4. Rotate the knurled ring on the left eyetube,

until the specimen is sharply focused for

the left eye. This corrects for any vision

diﬀerences between your right eye and left

eye.
