L-PCX256 140 mm Dia. Plano-Convex Lens; EFL=250mm Uncoated

The L-PCX256 is a Plano-Convex lens with a diameter of 140 mm, sourced from the renowned optical vendor, Ross Optical. This lens is specifically designed for use in spherical optical systems and features a base shape of a circle. The lens's geometry includes a thickness edge of 3.8 mm and a thickness center of 24.3 mm, providing a robust structure suitable for various applications.

The effective focal length (EFL) of this lens is 250 mm, making it ideal for systems that require a longer focal length. The lens's inner radius is 0 mm, and the outer radius is also 0 mm, indicating a uniform curvature. The radius of curvature (R1) is 129.2 mm, and the back focal length (BFL) is 234.92 mm, providing precise optical control.

The L-PCX256 lens is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties. This material is particularly suitable for applications that require high homogeneity and low auto-fluorescence. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, and uncoated lenses can be beneficial in certain scenarios due to their lower cost and simpler manufacturing process.

This lens is designed to work with a wavelength of 587.6 nm, making it suitable for applications that use this specific wavelength, such as certain types of fluorescence microscopy. The lens is in stock and ready for immediate use, as indicated by the valid weblink status.
