L-BCX230 50.8 mm Dia. Double-Convex Lens; EFL=38.1mm Uncoated

The L-BCX230 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 double-convex shape, meaning it has two spherical surfaces that curve outwards. This design is characterized by its "R1" and "R2" parameters, which in this case are equal to 34.44 mm and -34.44 mm respectively. These values represent the radii of curvature for the first and second surfaces of the lens. The lens's center thickness is 25.36 mm, while its edge thickness is 3 mm, providing a robust structure that can withstand typical use.

The effective focal length (EFL) of the L-BCX230 is 38.1 mm, a critical parameter that determines the lens's focusing power. This EFL, combined with the lens's diameter, makes it suitable for various applications that require a balance between field of view and focus.

The lens is made from N-BK7 Schott, a high-grade optical glass known for its excellent optical properties. This material is particularly suitable for applications that require high transmittance and low dispersion, such as imaging systems, beam shaping, and laser applications.

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.
