LE4484 25.4 mm Dia. UVFS Positive Meniscus Lens; EFL=500mm Uncoated

The LE4484 is a spherical lens from Thorlabs, featuring a positive meniscus design with a diameter of 25.4 mm. This lens is specifically designed for use in the ultraviolet-visible-near-infrared (UVFS) spectral range, making it suitable for a wide range of optical applications.

The lens has an effective focal length (EFL) of 500mm, which is the distance from the lens's center to the focal point where light rays converge. This long EFL makes the LE4484 ideal for use in systems requiring high magnification or narrow field of view.

The lens geometry includes an edge thickness of 2 mm and a center thickness of 2.4 mm. The inner and outer radii are both 0, indicating a symmetrical design. The back focal length (BFL) is 497.8 mm, which is the distance from the rear surface of the lens to its focal point.

The LE4484 is made from UVFS material with a Mal-1965 material ID. This material is known for its high transmittance in the UVFS range, ensuring optimal performance in these wavelengths. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

This lens is currently in stock and can be purchased directly from Thorlabs via the provided web link. With its robust design and high-performance characteristics, the LE4484 is an excellent choice for researchers and engineers seeking a high-quality UVFS lens for their optical systems.
