It is a fixture for automatically rotating the polarized wavefront preserving optical fiber.
Because the fixture rotates based on the Clad portion of the optical fiber, the position deviation of the optical fiber during rotation is very small.
The Clad part is fixed by vacuum suction by a vacuum pump, and the jacket part 2 is fixed by magnetic force. The motor uses a stepping motor with a resolution of 0.247. Corresponding to three jacket outer diameters of 250 μ m, 400 μ m and 900 μ m. Equipped with left and right reverse products.
