Fiber tips are microcomponents that can be formed directly at the end of an optical fiber to change the emission behavior of the fiber.
The interest in such optical fiber tips is growing significantly: This technology is becoming standard in many medical and industrial applications because it increases the efficiency of entire systems. This increase results from the reduction in optical interfaces; in addition, the compact design compared to separate optical systems is also an advantage. Cumbersome adjustment is no longer necessary: fiber tips are adjustment-free. Even external mechanical influences, such as vibrations or temperature fluctuations, do not affect the optical performance.
Diffusor tips disperse the light evenly across the length of the fiber tip. The diffusors are manufactured by carving spiral-shaped grooves into the fiber cladding with the help of CO2 lasers.
The diffusor tips ensure an even dispersion and are, therefore, well suited for applications, such as photodynamic therapy or tissue removal in urology.
These fiber tips are manufactured by our partner Polymicro Technologies in Phoenix, Arizona. Step-index, multi-mode fibers with a numerical aperture of 0.22 or 0.37 and a fiber core diameter > 200 µm are used for this purpose. Different buffer materials, connector types, and claddings are also available.
