SLB-40-100P 40.0 mm Dia. x 100.0 mm FL; Plano-Convex Lens Uncoated

The SLB-40-100P is a Plano-Convex lens, a type of spherical lens, sourced from OptoSigma. This lens, with a 40.0 mm diameter, is designed for use in a variety of optical systems. The lens has a center thickness of 6 mm and an edge thickness of 2 mm, providing a solid base for its use.

The effective focal length (EFL) of this lens is 100.0 mm, a length that determines the lens's magnification power. The back focal length (BFL) is 96 mm, which is the distance from the lens's rear surface to its focal point. The radius of curvature (R1) of the convex surface is 51.9 mm.

The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material makes the lens suitable for use in a wide range of applications, including laser systems, beam shaping, and imaging systems.

The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in certain applications where the user does not want to alter the lens's inherent properties. However, it's important to note that uncoated lenses can suffer from reflective losses, which can be as high as 4% per surface in the visible spectrum.
