LASER PROBE TIP
A probe tip for communicating and laterally directing electromagnetic radiation comprises a waveguide, a primary capsule, a compressible member and a malleable secondary capsule. The waveguide is configured to communicate electromagnetic radiation and includes a beveled surface at a distal tip for redirecting electromagnetic radiation in a lateral direction. The primary capsule is attached over the distal tip of the waveguide. The compressible member covers a portion of the primary capsule. The malleable secondary capsule is positioned over the primary capsule and the compressible member, and includes a crimp that compresses the compressible member against the primary capsule and secures the secondary capsule to the primary capsule.
