KBC043 25.4 mm Dia. x -50 mm FL; Uncoated; Double-Concave Lens

The KBC043 is a high-quality spherical lens, specifically designed for use in optical systems that require a concave-concave lens shape. This lens, sourced from the reputable vendor MKS/Newport, boasts a diameter of 25.4 mm and a focal length of -50 mm, making it suitable for a wide range of applications.

The lens is made from N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and high transparency in the visible spectrum. The base shape of the lens is circular, and it features a double-concave geometry, with radii of curvature R1 and R2 at -52.103 mm and 52.103 mm respectively. This geometry results in a back focal length (BFL) of -50.81 mm.

The lens has a central thickness of 2.5 mm and an edge thickness of 5.04 mm, providing robustness and durability. Despite its robust construction, the lens remains lightweight, making it ideal for use in portable or handheld devices.

The KBC043 lens is uncoated, offering users the flexibility to apply their own coatings to suit their specific application requirements. This feature, coupled with its high-quality construction and reliable performance, makes the KBC043 a versatile and valuable addition to any optical system.
