How to choose lens
Lens A：
Focus range：12mm-320mm，
Magnification：4.5-180x（with3 times digital zoom)
Applications ： observe whole size or part of coins, stones/stamps collect,
circuit board observe etc.

6
（Pic 5 Use lens A to see a coin）
Steps：In pic 5 it marked out which parts of the microscope are involved to each step.
①Install and fix lens A to the bottom of the focusing tube.
②Place the black or white backdrop board to the loophole on the stage, then place the coin on the
stage.
③Bend the two goose-neck spot lights, make sure the light shines on the coin.
④Loose the arm locker, located the whole monitor part to a desire height, meanwhile adjust the
height of the mechanical stage, make sure the final object distance is within 12mm to 320 mm. The
shorter the object distance is, the bigger magnification is.
⑤Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to
zoom out.
*In order to observe part of the coin, please lower the arm height to shorten the object distance,
then turn the focusing tube, get a clear image.
*Steps above can also be applied to observe plants, stones etc.

（Pic 6 go with Lens B&C）
Steps：In pic 6 it marked out which parts of the microscope are involved to each step.
①Install and fix the nosepiece set with Lens B&C to the bottom of the focusing tube.
②Place the translucent backdrop board to the loophole on the stage, and place slides on it.
③Remove the two USB spot lights.
④Loose the arm locker, located the whole monitor part to a desire height, meanwhile adjust the
height of the mechanical stage, make sure the final object distance is within 7-8mm(lens B). The
shorter the object distance is, the bigger magnification is. Or if you want to zoom in even more,
revolve the nosepiece to lens C and make the object distance within 3-4mm. The shorter the object

distance is, the bigger magnification is.
⑤Turn the focusing tube to get a clear image. Turn it clockwise to zoom in and the other way to
zoom out. Or, we recommend users to gently adjust the stage height to get a clear image, this
way causes less shake.
*Lens B&C’s magnification is quite big, which requires a short object distance. Meanwhile, any
tiny movement or shake of specimen would be displayed as huge on the monitor, which
requires user to operate very carefully and patiently.
