Polarising microscope with 360° rotatable stage - ideal for mineralogy, geology In contrast to usual light, polarized light has a preferred vibration plane of the light waves. Polarized light lets be seen anisotropic objects, whose observable properties are depending on the direction, ""in a new light"": crystals, but also animal hairs, feathers, muscles, nerve fibres and vegetable cell walls, which have a preferred direction of its biomolecules, show structures now, which were hidden in the normal bright field image. Images made by polarized light are often characterized by a fantastic coloring. Polarization microscopes are used particularly in mineralogy, geology, biology and medicine. In order to change the object's direction in a controlled way, the Science MPO 401 has a round, center-adjustable and full rotatable object stage with degree scale. The illumination and observation unit encloses e. g. the halogen bulb lamp (20 W) with dimmer, the field diaphragm (used to achieve the Köhler illumination), the 360° rotatable polarizer (for the production of polarized light), centering implements for the objectives and the analyzer attachment (for the analysis of the polarized light). The analyzer attachment is meant for receiving the 360° rotatable analyzer and optional available sliders (Bertrand lens for conoscopy; quartz wedge, lambda plate and lambda/4 plate used in order to get special colour effects). The wide field eyepieces (WF10x), which are also optional available, are placed at the trinocular head with an inclination of 30°.
