The AX2540-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 thick edge and a 15.7 mm thick center. The axicon's alpha angle is 0.6981317007977318 radians, or approximately 40 degrees, providing a high level of convexity.
The Axicon Prism is constructed from UVFS, a material with a catalog number of MAL-1965. This material is specifically designed for use in the 1310 nm wavelength range, making it ideal for applications in this spectrum.
The AX2540-C is coated with a front AR coating, identified as THo C Bbar. This coating is designed to reduce reflection and improve transmission in the 1050-1700 nm wavelength range. The prism's shape, combined with its specific material and coating, make it a versatile and high-performing optical element.
