LB1596-A N-BK7 Bi-Convex Lens; Dia:1 in; f=60.0 mm ARC 350-700nm
The LB1596-A is a high-quality bi-convex lens, designed and manufactured by Thorlabs. This lens is part of the Spherical Lens (Convex-Convex) category, featuring a circular base shape and a diameter of 1 inch (25.4 mm). The lens's edge thickness measures 2 mm, while the center thickness is 4.7 mm, providing a robust and durable structure.
The lens's effective focal length (EFL) is 60 mm, and the back focal length (BFL) is 58.4 mm, making it suitable for a wide range of optical applications. The radii of curvature for the first and second surfaces are 61 mm and -61 mm, respectively. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The LB1596-A lens is coated with tho a bbar on both the front and back surfaces, enhancing its performance in the 350-700 nm wavelength range. This coating reduces reflection and increases transmission, making the lens ideal for use in laser applications and other settings where high transmission is required.
