L-BCX129 25.4 mm Dia. Double-Convex Lens; EFL=75.6mm Uncoated

The L-BCX129 is a high-quality double-convex lens offered by Ross Optical, a renowned vendor in the optical industry. This lens, with a diameter of 25.4 mm, is designed for use in a variety of optical applications, thanks to its precise geometry and material composition.

The lens features a large effective focal length (EFL) of 75.6 mm, making it suitable for use in systems that require a longer focal length. The double-convex shape, characterized by two convex surfaces, provides a strong converging effect, focusing light to a single point. This shape is defined by the radii of curvature, R1 and R2, which are 77.26 mm and -77.26 mm respectively.

The L-BCX129 is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. This material is known for its low dispersion, high transparency, and excellent homogeneity, making it an ideal choice for many optical applications.

The lens has a thickness of 3 mm at the edge and 5.1 mm at the center, providing structural integrity while minimizing unnecessary weight. The geometry of the lens is circular, allowing for a wide range of applications and ease of integration into various systems.

Notably, this lens is uncoated. While coatings can be applied to enhance the lens's performance in specific applications, such as reducing reflection or increasing durability, this lens is designed to provide optimal performance in its uncoated state.
