LE1418 50.8 mm Dia. N-BK7 Positive Meniscus Lens; EFL=150mm Uncoated
The LE1418 is a spherical lens with a base shape of a circle, designed and manufactured by Thorlabs. This lens falls under the category of a positive meniscus lens, characterized by a convex-concave shape. The lens has a diameter of 50.8 mm, making it suitable for a wide range of applications.
The lens has a center thickness of 7.3 mm and an edge thickness of 2.7 mm, providing a robust structure. The effective focal length (EFL) of this lens is 150 mm, which is a crucial parameter for determining the lens's focusing power. The first radius of curvature (R1) is 47.9 mm, and the second radius of curvature (R2) is 119.3 mm. These radii of curvature, along with the EFL, contribute to the lens's optical performance.
The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties. The wavelength for this lens is 587.6 nm. The lens does not come with any coating, as indicated in the item data.
