Darkfield Condenser Lens
The purpose of the condenser lens is to focus the
light onto the specimen.
A darkfield condenser can offer bright images against
a dark background of otherwise difficult to view
specimens. The darkfield condenser is popular for
gem studies.
Darkfield condenser lenses do not come standard with SM models unless
they have “-DK” in the SKU number.
Dimmers
Controls the amount of light that
escapes from the illumination
source. You can control the top
and bottom lights separately. The
knobs are on the base.
Diopter
A small ring on one of the eyetubes, used to focus
that ocular lens (eyepiece).
When you are focusing a microscope, you focus one
eye at a time. With one eye shut, you focus the
objective lens first, using the focusing knobs. Then
you focus the other eyepiece using the diopter ring.
Eye Guards
Eye Guards fit over the eyepieces, they are for
comfort only.
