14APX-1-140-1 25.4 mm Dia. N-BK7 Standard Plano-Concave Axicon; t=8 mm Uncoated

The 14APX-1-140-1 is a standard plano-concave axicon prism from Standa, a renowned vendor in the optical industry. This axicon prism, with a catalog number 14APX-1-140-1, is a specialized optical component designed for specific applications, particularly in the generation and manipulation of Bessel beams.

The prism features a base shape of a circle, with a diameter of 25.4 mm, providing a substantial surface area for light interaction. The axicon's thickness at the edge is 8 mm, contributing to its robustness and stability in optical systems. The apex angle of this axicon is 2.443460952792061 degrees, which is a critical parameter in determining the properties of the Bessel beam it generates.

The axicon is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The refractive index of this material at the specified wavelength of 633 nm is not provided, but it can be obtained from the Schott glass catalog. The axicon is uncoated, meaning it does not have any additional layers to alter its optical properties. This can be beneficial in certain applications where the natural properties of the glass are desired.
