Leica Microsystems Semi-automated instrument for polarisation tasks
Germany – Leica has recently launched the Leica DM4 P polarisation microscope for the investigation of crystalline structures such as minerals, plastics and polymers, drugs and pharmaceuticals, pigments and cement.
The Leica DM4 P is fully coded and semi-automated, and can be configured with either transmitted light axis or incident light axis as well as with both light axes. This makes the instrument an ideal tool for all polarisation tasks, the company says.
Users benefit from LED illumination which lights samples homogeneously and at a constant colour temperature at all microscope settings. It is claimed that strain-free optics and objectives guarantee that birefringence stems from the samples – not from the optics. Leica adds that the optional equipment with coded Bertrand lens and magnification changer provides optimal results for conoscopic observation.
