A dark field microscope is ideal for viewing objects that are
unstained, transparent and absorb little or no light. These
specimens often have similar refractive indices as their
surroundings, making them hard to distinguish with other
illumination techniques. You can use dark field to study marine
organisms such as algae, plankton, diatoms, insects, fibers, hairs,
yeast and protozoa as well as some minerals and crystals, thi
polymers and some ceramics. You can also use dark field in the
research of live bacterium, as well as mounted cells and tissues.
It is more useful in examining external details, such as outlines,
edges, grain boundaries and surface defects than internal
structure.

is optional)
OBJECTIVES
All optics are anti-fungus treated and anti-reflection coated for
maximum light throughput
Infinity achromatic objectives 4x/0.13 10x/0.30 20x/0.40 S40x/0.70
S100x/1.25 oil (Optional)
Infinity E-Plan objectives 4x/0.10 10x/0.25 20x/0.40 S40x/0.65

STAGE
• 156 x 138 mm ceramic stage with integrated 76 x 54 mm mechanical
stage protects with a very tough ceramic surface, against marks and
scratches.The surface also ensures stray light not to be reflected
from the stage into the objective
• 185 x 177 mm rackless stage equipped with double slide holder and
integrated 75 x 50 mm rackless mechanical stage. It has no
protruding parts, enabling more smooth movements and is safer
(Optional)
CONDENSER FOR DARK FIELD
Dark field condenser is based on an Abbe, aplanatic, or achromatic
condenser, but to the light path add a dark field stop. This
additional element is housed in various ways.
• Dark field condensr (dry) usually for 40-600X manification.
• Dark field condensr (oil), if you want to observe 600X and more,
this condenser is necessary.
FOCUSING
• Coaxial coarse and fine adjustments, 100 graduations, 1 μm per
graduation, 100 μm per rotation, total travel approximately 14
mm.(most to 25mm)
• Supplied with an adjustable rack stop to prevent damage to sample
and objectives.
• The coarse adjustments are equipped with friction control
ILLUMINATION
• 3 W adjustable LED illumination with internal 100-240 V power
supply
• The innovative design offer larger apertures, allowing the
optical system of the microscope to produce images at higher
resolutions,
very close to the theoretical diffraction limit of the optics.
Other benefits of the NeoLED is the low energy consumption, no
heating and a long operating lifetime
• The illumination on models with IOS plan and plan phase infinity
corrected system provides high contrast and a maximum achievable
resolving
power of the optics. Also available for other models as an option
PACKAGING
• Supplied with power cord, dust cover, a spare fuse, user manual
and 4 ml immersion oil for models with S100x objective.
• All packed in good quality foam and carton.
