The AX122-C is a specialized optical component, specifically an Axicon Prism, sourced from Thorlabs. This prism, with a diameter of 12.7 mm, is designed for use in the 1310 nm wavelength range. The prism's unique geometry, characterized by a small angle (alpha) of 0.03490658503988659 radians and a convex shape, makes it suitable for a variety of applications.
The AX122-C has a thickness of 5 mm at the edge and 5.2 mm at the center. This slight curvature, or convexity, is a key feature of Axicon Prisms, enabling them to focus or collimate light in a ring-shaped pattern. The prism's material is UVFS, which has a refractive index suitable for the specified wavelength range.
The prism's coating is another critical aspect. The front surface of the AX122-C is coated with a broadband anti-reflective coating (AR), designed for the 1050-1700 nm range. This coating reduces surface reflections, enhancing the prism's transmission efficiency and overall performance.
