L-PCX296 50 mm Dia. Plano-Convex Lens; EFL=400mm Uncoated

The L-PCX296 is a Plano-Convex lens with a diameter of 50 mm, sourced from the renowned optical component vendor, Ross Optical. This lens is specifically designed for use in applications where a long effective focal length (EFL) is required. The EFL of this lens is 400mm, making it suitable for use in systems where a high degree of magnification or a narrow field of view is necessary.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes the lens suitable for use across a wide range of wavelengths, with a specified wavelength of 587.6 nm. The lens is uncoated, which means it does not have any anti-reflective coatings. This may result in higher reflective losses, but it also means that the lens is less susceptible to damage from environmental factors.

The lens has a base shape of circular, with a thickness at the edge of 2.5 mm and a thickness at the center of 4 mm. The inner radius is 0 mm, and the outer radius is also 0 mm. The lens's geometry is spherical, with a radius of curvature (R1) of 206.72 mm and a back focal length (BFL) of 398.7 mm.

According to the vendor's website, this lens is currently in stock, making it readily available for immediate use. For more information about this lens, including pricing and availability, please refer to the provided weblink.
