SLB-30-40P 30.0 mm Dia. x 40.0 mm FL; Plano-Convex Lens Uncoated

The SLB-30-40P is a Plano-Convex lens with a diameter of 30.0 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 is characterized by its spherical shape, with a center thickness of 8.4 mm and an edge thickness of 2 mm. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a plano surface on one side and a curved surface on the other. The effective focal length (EFL) is 40 mm, and the back focal length (BFL) is 34.5 mm. The radius of curvature (R1) is 20.76 mm.

The lens is uncoated, which means it does not have any anti-reflective coatings. This may result in higher reflective losses, but it also means that the lens can be used in a wider range of wavelengths without the risk of coating damage. The lens is designed to operate at a wavelength of 546.1 nm.
