L-BCX226 50 mm Dia. Double-Convex Lens; EFL=400mm Uncoated

The L-BCX226 is a spherical lens with a base shape of circular and a double-convex design, sourced from the reputable vendor Ross Optical. This lens boasts a diameter of 50 mm and a center thickness of 4 mm, with a slightly thinner edge thickness of 2.5 mm. The lens's effective focal length (EFL) is 400 mm, making it suitable for applications requiring a longer focal length.

The lens's first radius of curvature (R1) is 412.76 mm, while the second radius (R2) is -412.76 mm, indicating a convex-convex design. The inner and outer radii are both 0 mm, suggesting a symmetrical lens design.

The L-BCX226 is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material is ideal for applications where high image quality and low distortion are critical.

The lens is designed to work with a wavelength of 587.6 nm, which falls within the visible light spectrum. It is uncoated, meaning it does not have any anti-reflective or other surface coatings. This may result in higher reflectivity and lower transmission compared to coated lenses, but it can also simplify the optical system and reduce costs.

Please note that the lens's specifications are subject to the limitations and tolerances of the manufacturing process. For detailed information on these tolerances, please refer to the vendor's catalog or contact their sales department.
