KBC013 6.35 mm Dia. x -6.3 mm FL; Uncoated; Double-Concave Lens

The KBC013 is a high-quality spherical lens, specifically designed for concave-concave applications. This lens, sourced from the reputable vendor MKS/Newport, boasts a 6.35 mm diameter and a center thickness of 2.5 mm, ensuring a compact and efficient design. The lens features an edge thickness of 3.75 mm, providing robustness and durability.

The KBC013 lens has an effective focal length (EFL) of -6.3 mm, making it ideal for use in optical systems that require strong negative lensing. The radii of curvature for the front and back surfaces are -6.861 mm and 6.861 mm respectively, contributing to its double-concave shape. The back focal length (BFL) is -7.02 mm, further emphasizing its negative focal properties.

This lens is made from N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and versatility. The lens is uncoated, providing a cost-effective solution for applications where coating is not a necessity. However, users should be aware that uncoated lenses may have higher reflectivity and lower transmission compared to coated ones.

The KBC013 lens is designed to operate at a wavelength of 589 nm, making it suitable for a wide range of applications. Its geometry and material properties make it a reliable choice for various optical systems.
