The AX1205-A is a 12.7 mm diameter Axicon Prism from Thorlabs, designed with a plano-convex geometry and a 5 mm AR coating optimized for the 350-700nm wavelength range. This Axicon Prism is a specialized optical element with a unique shape that focuses light into a thin line, making it ideal for applications such as laser beam shaping, beam collimation, and beam homogenization.
The prism's base shape is circular, and it features a convex surface with a small angle (alpha) of 0.008726646259971648 radians. The thickness of the prism at the edge and center are both 5 mm and 5.1 mm, respectively, ensuring excellent optical performance and minimal optical loss. The UVFS material, with the catalog number MAL-1965, provides excellent transmission in the specified wavelength range.
The AX1205-A prism comes with an anti-reflective coating on the front surface, which significantly reduces unwanted reflections and improves overall transmission. This coating is identified as THo A BBAR, which stands for Thorlabs' broadband anti-reflection coating. The coating is designed to provide high transmission and low reflectance across the 350-700nm wavelength range.
