LA1509-B N-BK7 Plano-Convex Lens; Dia:1 in; f=100.0 mm ARC 650-1050nm
The LA1509-B is a high-quality plano-convex lens, part of Thorlabs' extensive catalog of optical elements. This lens boasts a diameter of 1 inch and a focal length of 100.0 mm, making it suitable for a wide range of applications.
The lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing.
The geometry of the lens includes a 25.4 mm diameter, a 2 mm edge thickness, and a 3.6 mm center thickness. The effective focal length (EFL) is 100 mm, and the radius of curvature (R1) is 51.5 mm. The back focal length (BFL) is 97.3 mm, and both the inner and outer radii are 0 mm.
The LA1509-B is coated with Thorlabs' BBAR coating, designed to reduce reflection and increase transmission in the 650-1050 nm wavelength range. This coating enhances the lens' performance in infrared applications.
