SLB-60B-170P 60.0 mm Dia. x 171.4 mm FL; Double-Convex Lens Uncoated

The SLB-60B-170P is a high-quality double-convex lens, sourced from the reputable optical vendor, OptoSigma. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications, thanks to its precise geometry and material composition.

The lens has a diameter of 60.0 mm, making it suitable for use in systems that require larger optical elements. The thickness at the edge of the lens is 3.0 mm, while the thickness at the center is 8.1 mm, providing a robust structure that can withstand typical use. The effective focal length (EFL) of this lens is 171.4 mm, which is a critical parameter in determining the lens's magnification and field of view.

The SLB-60B-170P is made from n-BK7 Schott, a high-grade optical glass known for its excellent optical properties. The first radius of curvature (R1) is 176.46 mm, and the second radius of curvature (R2) is -176.46 mm, indicating a biconvex lens. The back focal length (BFL) is 168.7 mm, which is the distance from the rear surface of the lens to its focal point.

This lens is uncoated, meaning it does not have any anti-reflective or other surface treatments. While this may result in higher reflective losses, it also means the lens can be used in a wider range of wavelengths, making it a versatile choice for many applications.
