Abstract
The technical parameters of minimally invasive diffuse diffusers are analyzed in the article on the distal part of the polymer optical fiber. Prototypes were made diffuse diffusers made of polymer optical fibers manufactured by Mitsubishi Rayon Corporation (Japan) of different lengths: SC-20 with a diameter of 500 μm and SC-10 with a diameter of 250 μm by machining their reflective shell to apply inhomogeneities and changes in the conditions of total internal reflection. The conducted research created a basis for the introduction of new methods of creation minimally invasive diffuse diffusers in the distal part of the optical polymer fiber.
