SLB-15-40P 15.0 mm Dia. x 40.0 mm FL; Plano-Convex Lens Uncoated

The SLB-15-40P is a Plano-Convex lens with a diameter of 15.0 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 includes a thickness edge of 2.0 mm and a thickness center of 3.4 mm. The effective focal length (EFL) is 40.0 mm, and the radius of curvature (R1) is 20.76 mm. The back focal length (BFL) is 37.8 mm, and the lens has no inner or outer radius, indicating a flat surface on the non-curved side.

The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may result in higher reflective losses and a lower transmission rate compared to coated lenses. However, uncoated lenses are often more cost-effective and suitable for applications where such losses are acceptable or can be mitigated.

The lens is designed to work with a wavelength of 546.1 nm, making it suitable for a wide range of optical applications. Its spherical shape ensures a high degree of optical accuracy and minimal aberrations.
