The 100X, 200X, and 400X work the same way as the 30X/50X–
you must touch the object with the tip of the lens housing to get a
focused image. In this case, the tip of the lens is a clear dome
with a small hole in it. The actual "lens" is inside this plastic
housing, and it sees whatever is lined up with the hole in the
plastic.
When you are using the 100X or 200X lens for the first time, it's easiest to get a focused image
of something flat (e.g. paper, fabric, or a prepared slide). Touch the tip of the clear dome to the
object you'd like to view. While continuing to touch the object, rotate the gray, grooved ring in
one direction. If the focus is not cleared up, try rotating the ring in the opposite direction. Keep in
the mind that several turns of the ring may be necessary to achieve the proper focus. Once the
lens is focused on the flat object, only slight adjustments will be necessary when viewing
different objects.
The 400X lens is best used for slides and other flat objects. Its
field of view is so small–only a half a millimeter–that it might
take you some practice to become proficient in getting well-
focused images with this lens.

How to Use the 1X Lens

The 1X lens is different from the other lenses in several ways:
It does not have its own lights, so it cannot be used as a "touch
lens."
Its magnification is variable–the closer the object is to the lens,
the higher the magnification. Objects that are far away will
actually appear smaller than they are in real life.
It can be used as a video camera and/or a document camera.
