LA1560-B N-BK7 Plano-Convex Lens; Dia:0.5 in; f=25.0 mm ARC 650-1050nm
The LA1560-B is a Plano-Convex lens, a type of spherical lens characterized by its single curved surface and a flat surface. This lens, sourced from the reputable vendor Thorlabs, is designed with a circular base shape and a diameter of 12.7 millimeters. The lens's edge thickness measures 1.8 millimeters, while the center thickness is 3.5 millimeters, providing a solid and robust structure.
The lens's effective focal length (EFL) is 25 millimeters, a crucial specification that determines the lens's magnification power. The front radius of curvature (R1) is 12.9 millimeters, and the back focal length (BFL) is 22.6 millimeters. The lens's inner and outer radii are both zero, indicating a uniform curvature across the lens surface.
The LA1560-B is made from N-BK7, a popular glass type in the optical industry known for its excellent optical properties. This lens is designed to work with a wavelength of 587.6 nanometers, making it suitable for a wide range of applications.
The lens features a broadband anti-reflection coating, denoted as "tho b bbar" for both the front and back surfaces. This coating enhances the lens's performance by reducing unwanted reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system.
