The AX1205-B 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 650-1050nm wavelength range. This Axicon Prism is part of the UVFS material category, specifically identified as UVFS mal-1965.
The prism features a base shape of a circle with a thickness of 5 mm at the edge and 5.1 mm at the center. The alpha value, which represents the angle between the prism's base and its refracting surface, is 0.008726646259971648 radians. The convexity of the prism is on the convex side, allowing for specific optical properties and applications.
The AX1205-B's coating includes a front AR coating (tho b bbar) that minimizes surface reflections, enhancing transmission in the specified wavelength range. This prism is available for purchase directly from the vendor's website, with the current status indicating that it is in stock.
