Polarizing microscopes
for geosciences and industry

The new Leica microscope series

is designed for all polarizing examinations: petrography, mineral­ogy, structure characterization and examination of liquid crystals.
Leica’s new polarizing microscopes are ideal for a wide range of
applications.

With versatile instrument options, Leica polarizing microscopes
are also an ideal match for industrial analysis and quality control,
such as analyzing glass, plastics, textiles and fibers or testing dis­plays in the semiconductor industry. Leica microscopes always
provide the most accurate and reliable results.

Specifically designed for your application:

• Leica DM4500 P for research and development

• Leica DM2500 P for routine polarization applications

• Leica DM750 P for university and other instructional use

Accurate results:

The new Leica polarizing microscopes will show you how easy
and reliable microscopy can be. Leica’s convenient operating
concept allows you to improve your workflow and concentrate
entirely on the task at hand.

Advantages that speak for themselves:

• Improved polarization contrast to obtain more information

from a sample

• Easy operation for accurate sample evaluation in both

orthoscopy and conoscopy

• Ergonomic design for user comfort

• Camera and software modules can be integrated for fast, easy,

and reproducible documentation

Leica DM4500 P

The Microscope that Guides You

• Automation that anticipates your next

work step:

– Automatic diaphragm setting and

light intensity

– Constant Color Intensity Control

for constant color temperature

– Condenser cap swings in and out

automatically

The right diaphragm – automatically

The Leica DM4500 P automatically detects which contrast method
and objective are being used. This provides valuable consistency
and reproducibility for your research. Manual diaphragm setting
is no longer required, either in the transmitted light or incident
light method. You can concentrate on your work – the Leica
DM4500 P takes care of the rest for you.

Always in the right light

Light intensity automatically adjusts to the objective. Image bright­ness remains constant when switching objectives, which elimi­nates glare. You can always adjust the light intensity manually as
well.

Constant color temperature

The Leica DM4500 P’s transmitted light axis is ideally suited for
mineralogical stone identification. Its Constant Color Intensity
Control automatically maintains a constant color temperature,
and you no longer need neutral density filters to compensate for
changes in light intensity.

Designed for use in research and development: the new
Leica DM4500 P – polarizing microscopy has never been
easier.

The correct condenser setting – immediately

All condensers are designed with condenser heads that are
perfectly matched optically and automatically swing in and out
depending on the objective magnification. They are effective from

1.25x–100x magnification.
