Leica Microsystems has launched the Leica DM4 P polarisation microscope for the investigation of crystalline structures such as minerals, plastics and polymers, drugs and pharmaceuticals, or pigments and cement. The Leica DM4 P is fully coded and semi-automated, and can either be configured with transmitted light axis or incident light axis, as well as with both transmitted and incident light axis. This makes the instrument suitable for all polarisation tasks.
Users benefit from LED illumination which lights samples homogeneously and at a constant colour temperature at all microscope settings. Strain-free optics and objectives guarantee that birefringence stems from the samples, not from the optics. In addition, the optional equipment with coded Bertrand lens and magnification changer ensures optimal results for conoscopic observation.
Users can store and recall information due to the coded components of the Leica DM4 P. While changing objectives, illumination intensity and aperture settings are automatically recalled by the Illumination and Contrast Manager. The coded six-fold nosepiece ensures that the acquired images are automatically calibrated, while the store and recall function in the Leica Application Suite software enables reproducible image settings.
