AX2505-C 25.4 mm Dia. UVFS Plano-Convex Axicon Prism; 5 mm AR 1050-1700nm

The AX2505-C is a 25.4 mm diameter Axicon Prism, part of Thorlabs' extensive catalog of optical elements. This Axicon Prism is designed with a plano-convex geometry, featuring a 5 mm thickness at the edge and a slightly increased thickness of 5.1 mm at the center. The Axicon's apex angle is 0.008726646259971648 radians, or approximately 0.5 degrees, providing a high level of precision.

The Axicon Prism is constructed from UVFS, a material with a refractive index suitable for a wide range of wavelengths, specifically designed for use in the 1310 nm range. This makes it an ideal choice for applications that require high-quality optical performance in this wavelength region.

The AX2505-C is equipped with an anti-reflection coating on the front surface. This coating, identified as "tho c bbar", is designed to reduce surface reflections and increase transmission, thereby enhancing the overall efficiency and performance of the optical system in which it is used. The coating is specifically tailored for the 1050-1700 nm wavelength range, further optimizing its performance in this spectral region.
