LB1409-C N-BK7 Bi-Convex Lens; Dia:1 in; f=1000.0 mm ARC 1050-1700nm
The LB1409-C is a high-quality bi-convex lens made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Thorlabs, is designed with a diameter of 1 inch and a focal length of 1000.0 mm, making it suitable for a wide range of applications.
The lens features a spherical shape, with both surfaces curved inward. The first surface has a radius of curvature (R1) of 1029.8, while the second surface has a radius of curvature (R2) of -1029.8. This design results in an effective focal length (EFL) of 300 mm and a back focal length (BFL) of 999.3 mm.
The lens is coated with a broadband anti-reflection coating, suitable for wavelengths between 1050 nm and 1700 nm. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens.
The lens has a center thickness of 2.6 mm and an edge thickness of 2 mm, providing structural integrity and resistance to damage. The lens is available for immediate purchase, as indicated by its "in stock" status on the vendor's website.
