SLB-30B-50P 30.0 mm Dia. x 51.1 mm FL; Double-Convex Lens Uncoated

The SLB-30B-50P is a high-quality double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications.

The lens has a diameter of 30.0 mm and a center thickness of 6.4 mm, ensuring a substantial light-gathering capacity. The edge thickness is 2.0 mm, providing structural rigidity. The effective focal length (EFL) of this lens is 51.1 mm, making it suitable for applications that require a longer focal length.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes the lens suitable for use in a wide range of wavelengths, including the visible spectrum.

The curvature of the lens is defined by its radii of curvature, with r1 being 51.9 mm and r2 being -51.9 mm. This double-convex design provides a wide field of view and low spherical aberration. The back focal length (BFL) of the lens is 48.9 mm, which should be considered when designing the optical system.

The lens is uncoated, which means it does not have any anti-reflective coatings. This might result in higher reflective losses and a lower transmission rate, but it also means that the lens is less susceptible to damage from environmental factors.
