14APX-1-160-1 25.4 mm Dia. N-BK7 Standard Plano-Convex Axicon; t=8 mm Uncoated

The 14APX-1-160-1 is a 25.4 mm diameter N-BK7 Standard Plano-Convex Axicon with a thickness of 8 mm, sourced from Standa. This axicon is a specialized optical element with a unique geometry that focuses light into a thin line. It is often used in beam shaping applications, such as generating Bessel beams or in laser material processing.

The apex angle of this axicon is 2.792526803190927 degrees, which is a crucial parameter in determining the beam's focus length and diameter. The convex side of the axicon has a curvature that starts at the apex and extends to the edge, providing a smooth transition for the light. The axicon is made of N-BK7, a popular optical glass known for its excellent optical properties and wide transmission range, making it suitable for use with a wavelength of 633 nm.

Notably, this axicon is uncoated. While coatings can enhance the performance of optical elements by reducing reflection losses or protecting the surface, an uncoated axicon can be advantageous in certain applications where the natural properties of the glass are desired. However, it may also be more susceptible to environmental factors such as dust or moisture.
