Details
Plano-convex axicons are conical lenses which are used for variety of applications. When used in pair with a conventional spherical lens, axicons can focus laser light into a ring shape with annular focus. This feature can be used in hole drilling, microscopy and medical applications. Another interesting feature of axicons is a possibility to transform a Gaussian beam into a non-diffractive Bessel beam in the near field. Bessel beams can be used in atom or molecule guiding applications.
Laserand offers two types of plano-convex axicons: regular and precision. Regular axicons will create annularly shaped beam. Precision axicons (item ID ending with -P, eg. 1-APX-2-B254-P) will also transform Gaussian beam into a Bessel beam. You can choose accordingly, depending on your specific application.
