AX72501-E3 25.4 mm Dia. ZnSe Plano-Convex Axicon Prism; 3.4 mm AR 7000-12000nm
The AX72501-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 element with a unique geometry that focuses or collimates light beams.
The prism's base shape is circular, and it features a precise convexity of 0.0017453292519943296 radians, or approximately 0.1 degrees. This convexity, combined with the 3.4 mm thickness at both the edge and center, contributes to the prism's ability to manipulate light beams effectively.
The AX72501-E3 is made from ZnSe (Zinc Selenide), a material with a high refractive index and excellent optical transmission in the infrared region. This makes it suitable for applications involving IR light sources.
The prism's coating is a front-side anti-reflection coating (AR), specifically the Thorlabs E3ZnSeARC7000-12000nm coating. This coating reduces surface reflections, enhancing the prism's overall transmission and performance.
