M620 Series

1. Place the specimen to be studied on a glass slide (or use a prepared slide). Place it on the stage,

holding it snugly in place with the metal slide holders (clips) of the mechanical stage.

2. Center the specimen over the stage opening, lining it up with the light and the objective lens.

3. To adjust the illumination, slowly turn the dimmer on the right side of the base until the desired

intensity of light is achieved.

1. Turn the nosepiece to choose an objective. It is easiest to use the lowest magnification first (4x

objective) to lo- cate and focus on the specimen. As you move up in magnification you may need to

refocus the image a little each time.

2. Being focusing by first looking with one eye through the eyepiece without the diopter. Close your

other eye. Use the coarse focusing knob to adjust the height of the stage until the sample comes into

clear focus.

Note: You may loosen the limit-stop knob (located on the read of the stage) in order to give yourself the

full range of motion for fine tuning the focus.

3. Once the image is clear in your field of view, you will want to use the fine focusing knob to tune it for

best results.

Note: Please be careful when moving the mechanical stage if you need to re-center the sample, or if

moving the stage very close to the objectives. The limit stop is designed to prevent impact between

objective and slide, so when it is off you will be able to damage the microscope.

1. By changing the aperture (hole size) of the iris diaphragm, you can adjust the background brightness.

Adjust the aperture of the iris diaphragm by rotating the disc underneath the stage to the desired

aperture.

1. To remove the 10x eyepiece included on the microscope, you will need to remove the small metal

screw on the ocular tube just under where the eyepiece connects to the tube. To do so, you will need a

1mm flathead precision screwdriver (much like what you would use to adjust eye glasses).
