The 130-0370 is a 30 mm diameter N-BK7 Standard Plano-Convex Axicon with an 8 mm uncoated edge, available from EKSMA Optics. This axicon features a base shape of a circle and is designed for use with a wavelength of 633 nm.
The axicon's geometry includes a diameter of 30 mm, a thickness at the edge of 8 mm, and a thickness at the center of 9.3 mm. The apex angle is 2.9670597283903604 degrees, and the convexity is on the convex side. The material used for this axicon is N-BK7 Schott, a popular choice for its excellent optical properties and high damage threshold.
The axicon is uncoated, which means it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where the natural properties of the material are desired. However, it's important to note that uncoated surfaces can be more susceptible to damage from environmental factors and handling.
