AX122-A 12.7 mm Dia. UVFS Plano-Convex Axicon Prism; 5 mm AR 350-700nm

The AX122-A is a 12.7 mm diameter Axicon Prism, a specialized optical component with a unique geometry that finds application in various fields, including laser beam shaping and beam collimation. Sourced from the renowned optical component manufacturer Thorlabs, this Axicon Prism is characterized by its plano-convex shape and a 5 mm thick edge, ensuring robustness and durability.

The Axicon Prism's unique feature is its angled face, or 'alpha', which is 0.03490658503988659 radians in this case. This angled face, combined with the prism's convex shape, allows for the creation of a focused, hollow beam when illuminated with a laser. The thickness at the center of the prism is 5.2 mm, slightly more than the edge, contributing to its overall structural integrity.

The AX122-A is fabricated from UVFS, a material with a refractive index suitable for use in the ultraviolet to near-infrared spectrum. This makes it an ideal choice for applications involving lasers with wavelengths within this range, specifically at 532 nm, as indicated in the item data.

The prism's front surface is coated with a broadband anti-reflective coating (AR), designed to minimize surface reflections and optimize transmission within the 350-700 nm range. This coating ensures that the maximum amount of light passes through the prism, enhancing the efficiency and performance of the optical system in which it is used.
