L-BCX228 50 mm Dia. Double-Convex Lens; EFL=750mm Uncoated

The L-BCX228 is a 50 mm diameter double-convex lens, sourced from the reputable optical vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, ensuring a high level of optical performance. The lens is circular, making it suitable for a wide range of applications.

The lens's geometry is meticulously crafted, with a thickness edge of 2.5 and a thickness center of 3.3. The effective focal length (EFL) is 750mm, indicating a strong magnification capability. The first radius of curvature (R1) is 774.64, while the second radius of curvature (R2) is -774.64, suggesting a symmetric design that can minimize optical aberrations.

The L-BCX228 lens is made from the high-quality material, n-bk7 schott. This material is known for its excellent optical properties, including high transparency and low dispersion, making it ideal for various optical applications. The lens is designed to work with a wavelength of 587.6 nm, ensuring optimal performance in specified conditions.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections and increasing transmission, an uncoated lens can be advantageous in certain situations, such as when cost-effectiveness or specific optical characteristics are priorities.
