Axicon Lens-Plano Convex
Plano-convex Axicon consists of one convex conical surface and one plane surface. It is always used to produce a non-diffractive ring-shaped beam in the near field, whose diameter will increase over distance while maintaining a constant ring thickness. When used with a collimated Gaussian beam, Plano-convex Axicon can create an approximation of a Bessel beam ideal for a range of medical, research, measurement, and alignment applications.
