LE4412 50.8 mm Dia. UVFS Positive Meniscus Lens; EFL=100mm Uncoated
The LE4412 is a spherical lens with a base shape of a circle, sourced from the reputable vendor Thorlabs. This lens is a positive meniscus type, characterized by its convex-concave design. The lens has a diameter of 50.8 mm, making it suitable for a wide range of optical applications.
The lens features an effective focal length (EFL) of 100mm, which is a crucial parameter in lens selection. The EFL determines the distance between the lens and the focal point where the light rays converge. This lens is uncoated, meaning it does not have any additional layers to enhance light transmission or protect the lens surface.
The geometry of the lens includes a thickness of 1.2 mm at the edge and 10.7 mm at the center. The radii of curvature are 30.6 mm for the first surface and 80.9 mm for the second surface. The back focal length (BFL) is 89 mm, and the inner and outer radii are 0 mm, indicating a flat inner and outer surface.
The LE4412 is made of UVFS material with the ID 1965. It is designed to work with a wavelength of 588 nm. This lens is currently in stock and available for immediate purchase through the provided web link.
