SLB-40B-60P 40.0 mm Dia. x 61.4 mm FL; Double-Convex Lens Uncoated

The SLB-40B-60P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications.

The lens has a diameter of 40.0 mm and a center thickness of 8.6 mm, making it suitable for applications requiring a substantial light-gathering capacity. The edge thickness is 2.0 mm, ensuring robustness and durability. The effective focal length (EFL) of this lens is 61.4 mm, which is a crucial parameter for determining the lens's focusing power.

The lens is made of n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The radii of curvature for the first and second surfaces are 62.28 mm and -62.28 mm, respectively, indicating a symmetrical design that can help minimize optical aberrations.

The back focal length (BFL) of this lens is 58.6 mm, which is the distance from the last surface of the lens to the image plane when the lens is focused at infinity. This information is crucial for designing optical systems that require precise image placement.

Please note that this lens is uncoated. While uncoated lenses can be cost-effective, they may have lower light transmission and are more susceptible to surface damage compared to coated lenses. However, they are often preferred in applications where specific coating properties are not required.
