LE4329 25.4 mm Dia. UVFS Positive Meniscus Lens; EFL=300mm Uncoated
The LE4329 is a spherical lens with a base shape of a circle, sourced from the reputable vendor Thorlabs. This lens is a positive meniscus type, featuring a convex-concave design. The lens has a diameter of 25.4 mm and a thickness at the edge of 2 mm, while the center thickness is slightly more at 2.6 mm. The effective focal length (EFL) of this lens is 300mm, making it suitable for applications that require a longer focal length.
The lens is made from UVFS material with the ID MAL-1965. The radii of curvature for this lens are R1 at 97.6 mm and R2 at 330.6 mm. The back focal length (BFL) is 297.5 mm, and both the inner and outer radii are 0 mm.
This lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide excellent optical performance, especially in applications where the coating might interfere with the desired optical effect.
The lens is designed to work with a wavelength of 588 nm. It is in stock and ready for immediate use. For more information, you can refer to the vendor's website through the provided weblink, which has been verified to be valid and up-to-date.
