SIDE-FIRING OPTIC FIBER TIP WITH LENGTH-BASED BEAM DIAMETER

摘要

An optic fiber (204, 304) having a core (208, 308) and a cladding (210, 310) surrounding the core. The core is coupled to a coreless rod (202, 302). The coreless rod has a free end defining a total internal reflection surface(216, 316). The coreless rod has a diameter (218, 318) that is greater than the diameter (220, 320)of the core. As light passes along the coreless rod, the diameter of the light increases. The light reflects off the total internal reflection surface of the coreless rod and exits through a side of the coreless rod.
