L-BCX160 38 mm Dia. Double-Convex Lens; EFL=45mm Uncoated

The L-BCX160 is a high-quality double-convex lens offered by Ross Optical, a renowned vendor in the optical industry. This lens, with a diameter of 38 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 45 mm, making it suitable for applications that require a longer focal length. The double-convex shape, characterized by two convex surfaces, is designed to refract and focus light efficiently. The first surface, with a radius of curvature (R1) of 44.67 mm, begins the refraction process, while the second surface, with an opposite curvature (R2) of -44.67 mm, completes the focusing of the light.

The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high transmittance across a wide spectrum. The lens's thickness at the edge is 2 mm, while the center thickness is 10.4 mm, providing structural integrity and minimizing optical aberrations.

Notably, this lens is uncoated. While coatings can enhance the lens's performance by reducing reflections, increasing transmission, and protecting the surface, an uncoated lens can be advantageous in certain applications where cost, simplicity, or specific optical characteristics are priorities.
