LE5714 25.4 mm Dia. CaF2 Positive Meniscus Lens; EFL=1000mm Uncoated
The LE5714 is a spherical lens with a base shape of a circle, designed and manufactured by Thorlabs. This lens is a positive meniscus lens, which means it has a convex-concave shape. The lens has a diameter of 25.4 mm and a thickness at the edge of 3.8 mm, while the center thickness is 4 mm. The effective focal length (EFL) of this lens is 1000mm, making it a long focal length lens.
The lens is made of Calcium Fluoride (CaF2) with the material ID mal-1963. This material is often used in optical systems due to its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties.
The lens has an inner radius of 0 and an outer radius of 0, which indicates that it is a simple lens without any additional features. The lens is designed to work with a wavelength of 4000 nm.
