Description
Lfiber's in-line fiber optic polarizer with high extinction ratio (460nm, 630nm, 780nm, 850nm, 980nm, 1064nm, 1310nm, 1550nm, and 2000nm) is a fiber polarization device which enables the transmission of one particular state of polarization (SOP) and suppresses the transmission of the orthogonal state. It is therefore commonly used to fix a polarization state in an optical system or to analyze the SOP of an optical wave.
A fiber optical polarizer is one of the fundamental components in many fiber systems that are highly dependent on the polarization of the light guided by the optical fiber. Lfiber’s in-line fiber optical linear polarizers feature low loss, ultra high ER, high stability and reliability.
