LC1439 N-BK7 Plano-Concave Lens; Dia:0.5 in; f=-50.0 mm Uncoated
The LC1439 is a plano-concave lens from Thorlabs, featuring a spherical geometry and a circular base shape. This lens is designed with a diameter of 0.5 inches (12.7 mm) and a thickness at the edge of 4.3 mm, while the center thickness measures 3.5 mm. The effective focal length (EFL) of this lens is -50 mm, making it suitable for a variety of applications.
The lens is made of n-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties. The concave surface of the lens has a radius of curvature of -25.7 mm, and the back focal length (BFL) is -52.3 mm. The lens does not have any coating, which is indicated by 'Uncoated' in its name.
This lens is intended for use with a wavelength of 587.6 nm. The 'Spherical' shape of the lens ensures that light rays passing through the lens are refracted evenly, making it suitable for a wide range of optical systems.
