L-BCX210 47 mm Dia. Double-Convex Lens; EFL=80mm Uncoated

The L-BCX210 is a high-quality double-convex lens offered by Ross Optical, a renowned vendor in the optical industry. This lens, with a diameter of 47 mm, is designed for use in a wide range of optical applications, thanks to its precise geometry and material composition.

The lens features a large effective focal length (EFL) of 80 mm, making it suitable for applications that require a longer focal length. The double-convex design, characterized by two spherical surfaces that curve outwards, provides a strong converging effect, focusing light to a single point. This design is particularly useful in imaging systems, beam shaping, and other applications where light must be focused or collimated.

The lens is made from N-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. This material ensures high transmittance across a wide spectrum, making the lens suitable for use with various wavelengths. The lens's geometry includes an edge thickness of 2 mm and a center thickness of 8.9 mm, providing robustness and stability.

Notably, this lens is uncoated. While coatings can enhance the lens's performance by reducing reflection, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications. For instance, uncoated lenses can be more cost-effective and are often used in applications where the elimination of internal reflections is not critical.
