Edmund Optics (EO) (Barrington, NJ), introduces its Plano-Convex (PCX) Axicons. The lenses, which feature one conical surface and one plano surface, produce a non-diffractive ring-shaped beam that increases in diameter over distance, while retaining a constant ring thickness. When Plano-Convex (PCX) Axicons are used in conjunction with a collimated Gaussian Beam, they create an approximation of a Bessel beam. Edmund’s Plano-Convex Axicons are available uncoated and with VIS coating in apex angles from 90° to 179°, with a diameter of 25.4 mm. Featuring a precision fused silica sub-
strate, Plano-Convex (PCX) Axicons are also available with an Ultraviolet-Anti-Reflection (UV-AR) coating. The Axicons have apex angles of 90° and 130°, and a diameter of 25.4 mm.
