Abstract
The utility model relates to a horizontal rotary type silver/silver iodide hollow optic fiber coating device, which comprises a height adjusting platform, a multi-way valve, a distilled water bottle, a silver ammonia solution bottle, a reducer solution bottle, an iodine solution bottle, an organic solvent bottle, a nitrogen bottle, a rotary piston, a bearing, a motor, a capillary tube, a constant temperature tube (horizontally arranged), an automatic temperature controller and a discard solution bottle. As a reactant is adjusted to a certain height by the height adjusting platform, the reactant can flow into the straight horizontal capillary tube at a constant velocity; during the chemical reaction, the capillary tube keeps rotating with the constant temperature tube, thereby avoiding uneven coating of a silver/silver iodide dielectric layer due to a centrifugal force or the gravity of a resultant silver when the capillary tube is in a bending status, and improving the transmission performance of the silver/silver iodide optic fiber.
