Wave Plate Paddle

thingiverse

The paddle is designed for a quarter-half-quarter wave plate - an in-fiber polarization adjuster using Thorlabs' 780-HP fiber. To attach the fiber, it was wrapped twice around the first and third paddles, and four times around the second paddle in the array. The paddle's rotational position alters the output polarization state of the fiber. The circular groove diameter for the fiber is approximately 62mm, with an OpenSCAD file provided to facilitate customization for various groove diameters.
