英语释义

1. an object resembling an optical lens with a conical surface that has no definite focal point
On a trip to Russia, Milchberg discovered that scientists there were using an odd, funnel-shaped “axicon” lens that brought laser beams into an elongated, needle-like focus instead of the sharp point that conventional lenses produce.
— Curt Suplee, Washington Post, 11 Sept. 1995
