A fiber optic probe that eliminates extreme tip temperatures by radiating laser energy in a radial, 360&#xb0; pattern from the surface of an exposed fiber optic tip is disclosed. In an embodiment, a fiber optic core is configured to operatively engage with a source of laser energy at a proximal end of the fiber optic tip, and, at a distal end of the fiber optic tip, includes a plurality of refracting surfaces configured to disperse laser energy in a radial pattern. In one embodiment, the refracting surfaces may be arranged as a plurality of annular prisms defined around the fiber core. In another embodiment, the refracting surfaces may be arranged as a plurality of concave lenses defined in the fiber optic tip. The temperature distribution of the disclosed probes is controlled and uniform, and may be tailored to radiate laser energy in any desired pattern which may be suitable to achieve an intended objective.

An anti-fog coating composition is described comprising an aqueous polymeric dispersion; a crosslinker, and a surfactant. The dried and cured coating composition does not exhibit fogging within 8 seconds after being soaked in 25&#xb0; C. water for 1 hour. In favored embodiments, the dried and cured coating composition does not exhibit fogging within 60 seconds after being soaked in 50&#xb0; C. water for 24 hours. Also described are articles comprising the dried and cured coating composition disposed on a substrate as well as a method a providing an anti-fog coating on a substrate.
