Fiber Aligner "FA1000S_FP"

Achieved fiber optic coupling efficiency of 98%! Collaboration model from Akira Furusawa's laboratory at the University of Tokyo.

The "FA1000S_θ" is a device designed to couple a laser beam propagating in free space into an optical fiber after passing through an aspheric lens, developed with the full cooperation of Professor Akira Furusawa's laboratory at the University of Tokyo. It features a two-axis θ adjustment mechanism that allows for independent adjustment of two orthogonal rotation axes without moving the fiber's entry point from the center of the sphere, thanks to specialized processing technology (spherical gimbal mechanism). This new mechanism simplifies alignment, which was previously very difficult, and ensures long-term stability. 【Features of the θ Axis Adjustment Mechanism】 ■ Spherical Gimbal Mechanism (Patent No. 5888775 granted) - A structure where the fiber's entry point aligns with the center of the spherical rotating element due to specialized processing technology. - The entry point experiences minimal positional shift even when angle adjustments are made. ■ High operability and long-term stability achieved - Adjustment screws use a fine pitch screw with very little backlash of 0.15mm. - Our unique soft lock mechanism provides high holding power after adjustments. *For more details, please download the PDF (English version) or contact us.
