White Paper: Basics Of Polarizing Microscopy

Transverse wave light whose vibration possess direction is called polarized light. Light from an ordinary light source (natural light) that vibrates in random directions is called nonpolarized light. In contrast, while light with vertical vibration that travels within a single plane is called linearly polarized light, circularly polarized light and elliptically polarized light are types of light in which the vibration plane rotates forward.
