Fiber Recoater PTR303
Thorlabs Vytran® fiber recoaters restore the coating on spliced fibers. Coating material is injected into the mold cavity through a channel in the top plate. Recoaters are available with automatic or manual mold assemblies. Manual recoaters use a hinged top that opens and closes manually; automatic recoaters use a pneumatic mold assembly and automatically inject coating material into the cavity. Both types use quartz molds. A special coating on the quartz mold plates prevents coating material from curing between the plates and avoids recoating defects. Each recoater uses a volumetric dispensing pump to inject the coating material. Automatic injection systems are available on PTR205, PTR303, and PTR304, while manual injection systems are available on PTR303B and PTR304B. The recoated fiber is then cured with ultraviolet (UV) light. Recoating restores the stripped fiber's coating and its original flexibility. Unlike standard heat-shrink protection sleeves, recoated fiber can be handled and coiled with the original fiber without endangering the splice. The process begins by placing the splice in the center of the mold assembly. Inserts in the fiber holding blocks secure it in position. Coating material is injected into the cavity and then UV-cured. By restoring spliced fiber to a condition similar to the original fiber, recoaters are well suited to manufacturing fibers subject to high stress or sensitivity, including submarine fiber cables, undersea communications cabling, fiber lasers, and distributed Bragg reflector (DBR) lasers.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
