Leica DM4 P Polarization Microscope

If you would like to investigate crystalline structures, polarization microscopy will serve you best. Whether it be minerals, plastics and polymers, drugs and pharmaceuticals, or pigments and cement, with our polarization microscopes you will see what interests you most as a researcher or in quality assurance.

Store and recall information with coded components

• • When you change objectives, illumination intensity and aperture settings are recalled with the Illumination Intensity Control and Contrast Manager.
  • Acquired images are always calibrated due to the coded nosepiece.

Identify interesting structures

• With the large 25-mm field of view you get a perfect overview.
• A lower magnification rather than the detailed view often reveals the specific information you need - just think of flow or deformation structures or zonation by cooling processes.

You need a few components to get what you aim for in polarization. These are the most important:

• • Strain-free optics, because you need to be sure that the observed birefringence results from the sample and not from the optics
  • LED illumination is crucial, because it lights the samples homogenously and at a constant color temperature
  • Polarizers will make birefringence visible and a rotatable stage enables you to align the sample and optical axis
  • You need a Bertrand lens for conoscopic observation of the optical axis and compensators for measurement tasks

Get to know step by step in this polarization tutorial.

LED illumination saves you money in many ways: It consumes less energy than halogen illumination, and does not need to be replaced, causing downtime of your instrument, because it has a lifetime of up to 25,000 hours. Further advantages:

• LED lights your samples homogeneously and at a constant color temperature, providing you with a realistic impression of your sample
• LED adjusts light intensity fast so you can work smoothly
• LED requires no daylight filter since the LED already provides constant light temperature of 4500 K
• LED produces little heat, and therefore  does not need a cooling fan
• LED lets you work undisturbed, because no cooling fan makes a noise around you

Get different sample information from different magnifications of the 6-objective nosepiece.

• Use a 2.5x overview objective to identify macro structures in your sample
• Change to 63x magnification for detailed investigations of optical properties by means of conoscopy
• Switch to 100x to inspect phase reactions along grain boundaries

By the way: The nosepiece is also coded, so that it supports you intelligently.
