The LA1259-B is a plano-convex lens with a diameter of 1 inch, designed for use in the 650-1050nm wavelength range. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.
The lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. It has a spherical shape, with a front surface radius of 1292mm and a back focal length of 2498.6mm. The lens's effective focal length (EFL) is 2500mm, making it suitable for applications that require a long focal length.
The LA1259-B has a thickness of 2mm at the edge and 2.1mm at the center, providing a robust structure while maintaining a low profile. The lens features broadband anti-reflection coating (ARC) on both surfaces, specifically designed for the 650-1050nm wavelength range. This coating reduces surface reflections, enhancing the lens's transmission efficiency and overall performance.
