KBC016 12.7 mm Dia. x -100 mm FL; Uncoated; Double-Concave Lens

The KBC016 is a high-quality spherical lens, specifically designed for use in optical systems that require concave-concave lenses. This lens, sourced from the reputable vendor MKS/Newport, boasts a 12.7 mm diameter and a focal length of -100 mm, making it ideal for applications that necessitate a negative focal length.

The lens is crafted from the renowned N-BK7 glass from Schott, a material known for its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-concave geometry, with radii of curvature R1 and R2 at -103.785 mm and 103.785 mm respectively. This geometry contributes to the lens's negative focal length and its ability to converge light rays.

The KBC016 has a center thickness of 2.5 mm and an edge thickness of 2.82 mm, providing a robust structure while maintaining a compact profile. The lens's clear aperture is 12.7 mm, and it has an effective focal length (EFL) of -100 mm. The back focal length (BFL) is -100.82 mm, and the lens has no inner or outer radius, indicating a uniform curvature.

This lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. The lens is designed to operate at a wavelength of 589 nm, making it suitable for a wide range of applications in the visible light spectrum.
