KBX010 6.35 mm Dia. x 6.4 mm FL; Uncoated; Double-Convex Lens

The KBX010 is a high-quality spherical lens, specifically a double-convex lens, sourced from the reputable vendor MKS/Newport. This lens is designed with a circular base shape and features a diameter of 6.35 mm and a center thickness of 4.96 mm. The edge thickness is 3 mm, providing a robust structure while maintaining a compact form factor.

The lens boasts an effective focal length (EFL) of 6.4 mm, making it suitable for a wide range of optical applications. The radii of curvature for the first and second surfaces are 5.619 mm and -5.619 mm, respectively, contributing to its double-convex design. The back focal length (BFL) is 4.47 mm, which is an important consideration for optical system design.

The KBX010 lens is made from the renowned material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. This material is particularly suitable for applications in the visible spectrum, with a wavelength of 589 nm specified for this lens.

Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating or utilize it in applications where coating is not required. However, users should be aware that uncoated lenses may have higher reflectivity, which could impact the performance of certain optical systems.
