Plano-Convex (PCX) Axicons

POSTED 03/08/2011

rong>Ideal for medical research, measurement and alignment  

Plano-Convex Axicons (PCX) from Edmund Optics Edmund Optics® (EO), the premier provider of optical components, introduces its new Plano-Convex (PCX) Axicons.  These unique lenses feature one conical surface and one plano surface.  They are used to 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. They are also ideally suited for use in laser-drilling and Optical Coherence Tomography (OCT.)
Maintains high level of non-diffractive Bessel beam properties
Bessel Beams are ideal for a wide range of medical research, such as optical injections and corneal surgery, as well as measurement and alignment applications.  A Bessel beam is a non-diffractive beam made up of rings that each have power equal to every other ring.  Bessel beams are purely theoretical in nature, as they require an infinite amount of energy, however, the output of a Plano-Convex (PCX) Axicon provides an accurate approximation of the beam because it exhibits and maintains a high level of non-diffractive Bessel beam characteristics. 
Available uncoated or with AR coatings
Edmund Optics' Plano-Convex (PCX) Axicons are available uncoated and with VIS coating in apex angles from 90º to 179º with a diameter of 25.4 mm.  Featuring a precision fused silica substrate, Plano-Convex (PCX) Axicons are also available with an Ultraviolet-Anti-Reflection (UV-AR) coating with apex angles of 90º and 130º and a diameter of 25.4 mm.  It is recommended that Plano Convex (PCX) Axicons be used in conjunction with one of our high quality beam expanders to ensure a beam diameter of at least 50% of the clear aperture (CA).  Plano Convex (PCX) Axicons are in-stock and available for immediate delivery for fast turnaround and excellent value.
