Introduction:
This biological microscope is well designed and sturdily built. It has high quality optics and precision mechanics which meet the requirements of junior and senior high schools. All objectives are parfocal, parcentered, and the 40x objective is spring loaded which prevents damage to the specimen and/or objective. The head rotates 360 .

Assembly:
No assembly required, objectives and eyepieces are pre-installed at the factory for your convenience.
Using your micoscope:
Connect the power cord to an outlet and turn on the power switch.
Note: some models are cordless, and do not require an electrical outlet for use. Open the diaphragm underneath the stage to its full open position. Place your slide on the stage and secure with the stage clips or optional mechanical stage.

Using your micoscope:
Select the 4x objective to “scan” and locate the image of your specimen, and then switch to the 10x objective. Use the coarse and fine adjustments to bring the specimen into focus. Now switch to the 40x objective and focus using the fine focus knob. View the image with the 40x objective as there is less depth of focus and this will assure parfocality when you use a lower power objective.
You may need to rotate the disc diaphragm or adjust the iris diaphragm (models S90004D and S90004E include an iris diaphragm) to get better contrast. To get the best contrast, use the diaphragm chart below:
Number on
Disc
1
2
3
4
5
Objective
4x
10x
40x
Diaphragm Size
Smallest in diameter, least amount of light
Larger then 1, more light
Larger then 2, more light
Larger then 3, more light
Largest, maximum light to objective
The 40x objective is a “dry” objective. Do not use immersion oil which makes the image blurred and difficult to clean.
The microscope is now ready for general use.
