This 34-131 optical lens, sourced from Edmund Optics, is a 5mm diameter, plano-convex spherical lens with a focal length of 20mm, specifically designed for use with a 1064nm wavelength. The lens is made from fused silica, a material known for its excellent transmission properties across a wide range of wavelengths, making it an ideal choice for various optical applications.
The lens features a laser-optimized V-coat coating on both the front and back surfaces, enhancing its performance in laser-based systems. This coating is designed to provide high transmission and low reflectivity at the specified 1064nm wavelength, ensuring optimal light transmission and reducing unwanted reflections.
The lens has a thickness of 1.5mm at the edge and center, providing a robust and compact design. The inner and outer radii are both 0mm, indicating a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 9.17mm, contributing to its focal length of 20mm.
The lens's geometry and material properties make it suitable for use in various applications, including laser systems, imaging systems, and other optical setups. The detailed specifications and high-quality construction ensure reliable and consistent performance, making it a valuable addition to any optical system.
