L-BCX234 50.8 mm Dia. Double-Convex Lens; EFL=76.2mm Uncoated

The L-BCX234 is a high-quality double-convex lens offered by Ross Optical, a renowned vendor in the optical industry. This lens, with a diameter of 50.8 mm, is designed for use in a wide range of optical applications, thanks to its precise geometry and material properties.

The lens features a large effective focal length (EFL) of 76.2 mm, making it suitable for applications 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 particularly useful in imaging systems, beam shaping, and other applications where light needs to be concentrated or diverged.

The L-BCX234 is made from N-BK7 Schott, a high-grade optical 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 has a thickness of 2.9 mm at the edge and 11.5 mm at the center, providing structural integrity and resistance to deformation. The inner and outer radii are 0, indicating a symmetrical curvature that contributes to the lens's optical performance.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmittance, or providing other benefits, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
