Abstract
A collimation lens and an optical module of the collimation lens. The collimation lens includes a front convex aspheric lens, a first polarizing filter, a Faraday rotation (FR) crystal, a second polarizing filter, and a rear convex aspheric lens. The front convex aspheric lens is coupled to a first end face of the collimation lens, and the rear convex aspheric lens is coupled to a second end face of the collimation lens. The first polarizing filter is coupled between the front convex aspheric lens and the FR crystal, and the second polarizing filter is coupled between the FR crystal and the rear convex aspheric lens.
