LA1074-D N-BK7 Plano-Convex Lens; Dia:0.5 in; f=20.0 mm ARC 1650-3000nm
The LA1074-D is a plano-convex lens, a type of spherical lens, with a circular base shape and a diameter of 12.7 millimeters. This lens is sourced from the reputable vendor Thorlabs, and it is currently in stock with valid web links provided for further information. The lens has a thickness of 1.8 millimeters at the edge and 4 millimeters at the center, with an effective focal length (EFL) of 19.9 millimeters.
The front and back surfaces of the lens are coated with tho d bbar, a type of anti-reflective coating that is designed to reduce surface reflections and increase transmission in the spectral range of 1650 to 3000 nanometers. The lens is made of n-bk7 schott, a popular optical glass that offers excellent optical properties, making it suitable for a wide range of applications.
The radius of curvature (R1) of the curved surface is 10.3 millimeters, and the back focal length (BFL) is 17.3 millimeters. The inner and outer radii are both zero, indicating a uniform curvature. This lens is a versatile and high-performing optical component that can be used in various applications, including but not limited to imaging, beam shaping, and laser systems.
