This is a 14APX-1-178-2-P 25.4 mm Dia. UVFS Precision Plano-Convex Axicon, a specialized optical element designed and manufactured by Standa. The axicon has a diameter of 25.4 mm and a thickness at the edge of 3.5 mm, making it suitable for a wide range of optical applications.
The apex angle of this axicon is 3.1066860685499065 degrees, which is a crucial parameter in determining the focusing properties of the beam. The convexity of the axicon is on the side facing away from the beam source, and it is uncoated, which means it does not have any additional layers of material to alter the optical properties of the surface.
The material of this axicon is UVFS, which is a type of glass specifically designed for optical applications. The catalog number for this material is UVFS Mal-1965. The axicon is designed to work optimally with a wavelength of 633 nm.
The axicon is a type of prism, specifically a Plano-Convex Axicon. This type of prism is characterized by having one flat surface and one curved surface, which in this case is convex. The axicon shape is particularly useful in applications where a beam needs to be focused or collimated in a precise manner.
