Polarization Maintaining Collimator
1064nm wide band
Fiber optic collimator is made up by capillary pigtail and G- Lens which aligned accurately. By the self-Focus of G-Lens, collimator can realize output a parallel beam or input the parallel Beam into the fiber.
Vfibre offer single fiber and dual fiber with single mode, multimode fiber or polarization Maintaining collimator with different working distance. It features Low insertion loss, Low back reflection, High environmental stability, it can be used for laser beam delivery systems, coupling the output of a fiber into a detector, beam expansion systems for lab and optical Module or optical researching and lab field.
