SLB-25.4-40P 25.4 mm Dia. x 40.0 mm FL; Plano-Convex Lens Uncoated

The SLB-25.4-40P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 40.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens geometry features a convex shape with a center thickness of 6.2 mm and an edge thickness of 1.9 mm. The effective focal length (EFL) is 40 mm, and the back focal length (BFL) is 36 mm. The radius of curvature (R1) is 20.76 mm. The lens is uncoated, offering a clear, unaltered view of the light path.

This lens is ideal for various applications, including beam shaping, collimation, and focusing. It is particularly suitable for use in the visible spectrum, with a specified wavelength of 546.1 nm. The lens is circular, allowing for versatile integration into optical systems.

Please note that the lens is uncoated, which may affect its performance in certain applications. Coatings can be added to enhance the lens's properties, such as improving its transmission, reducing reflection, or increasing its durability.
