AX7252-E3 25.4 mm Dia. ZnSe Plano-Convex Axicon Prism; 3.4 mm AR 7000-12000nm

The AX7252-E3 is a 25.4 mm diameter ZnSe Plano-Convex Axicon Prism with a 3.4 mm AR coating optimized for the 7000-12000nm wavelength range. This axicon prism, sourced from Thorlabs, is a specialized optical component with a unique geometry that focuses or collimates light beams.

The prism's base shape is circular, and it features a convex surface with a small angle (alpha) of 0.03490658503988659 radians. This specific model has a thickness of 3.4 mm at the edge and 3.8 mm at the center. The axicon's design allows it to convert a Gaussian beam into a Bessel beam, which maintains its cross-sectional shape over a longer distance compared to a Gaussian beam.

The AX7252-E3 is made of ZnSe (Zinc Selenide), a material with a high refractive index and excellent transmission properties in the infrared region. The prism's coating, identified as "tho e3znsearc7000120", is a broadband anti-reflection coating that reduces surface reflections, enhancing the prism's performance in the specified wavelength range.

This axicon prism is a versatile and high-performance optical component, ideal for various applications, including beam shaping, laser beam collimation, and non-imaging optics. The AX7252-E3 is currently in stock, and more information about this product can be found on Thorlabs' official website.
