Bresser Science MPO 401 MicroscopeBresser Science MPO 401 Microscope The BRESSER Science MPO 401 Microscope uses polarized light. This light has a preferred vibration plane of light waves. Polarized light allows anisotropic objects to be viewed, whose observable properties are depending on the direction, in a new light. This works well with crystals, animal hairs, feathers, muscles, nerve fibers and vegetable cell walls, all which have a preferred direction of its biomolecules, and
