The LA1031-A is a high-quality plano-convex lens from Thorlabs, designed with a spherical surface and a circular base shape. This lens is fabricated from N-BK7, a popular glass type known for its excellent optical properties, particularly its low dispersion and high Abbe number. The lens has a diameter of 30.0 mm and a thickness of 2.5 mm at the edge, while the center thickness measures 4.7 mm.
The LA1031-A lens boasts an effective focal length (EFL) of 100.0 mm, making it suitable for a wide range of optical applications. The front and back surfaces of the lens are coated with ARC 350-700nm coating, which reduces reflection and enhances transmission within the specified wavelength range. This coating ensures optimal performance and minimal loss of light, making the lens an excellent choice for applications that require high transmission and low reflection.
The lens's geometry includes an inner radius of 0 mm and an outer radius of 0 mm, indicating a flat inner surface and a curved outer surface. The radius of curvature (R1) is 51.5 mm, and the back focal length (BFL) is 96.5 mm.
