1. Two polarizing elements in a polarized light microscope. The polar placed between the light source and substage condenser is called the polarizer, the polar placed between the objective and ocular is called the analyser. The vibration directions of the two polars may be crossed 90 degrees, to achieve crossed polars, slightly uncrossing one polar gives slightly uncrossed polars, removing the analyser results in plane-polarized light.
