KBC034 25.4 mm Dia. x -150 mm FL; Uncoated; Double-Concave Lens

The KBC034 is a high-quality Spherical Lens, specifically designed with a Double-Concave structure. This lens, sourced from the reputable vendor MKS/Newport, is a part of their extensive Uncoated N-BK7 Bi-Concave Lenses collection.

The lens boasts a diameter of 25.4 mm and a center thickness of 2.5 mm, with an edge thickness of 3.34 mm, providing a robust and durable structure. The base shape is circular, ensuring uniform light distribution and minimal distortion.

The KBC034 features an effective focal length (EFL) of -150 mm, making it ideal for applications requiring strong converging or diverging lenses. The first radius of curvature (R1) is -155.466 mm, while the second radius (R2) is 155.466 mm, indicating a symmetrical double-concave design. The back focal length (BFL) is -150.82 mm, further emphasizing its powerful diverging capabilities.

The lens is crafted from N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility. It is designed to work optimally with a wavelength of 589 nm. The KBC034 does not come with any coating, offering a bare, unaltered glass surface that can be customized according to specific application requirements.
