SLB-07B-15P 7.0 mm Dia. x 15.4 mm FL; Double-Convex Lens Uncoated

The SLB-07B-15P is a 7.0 mm diameter double-convex lens, uncoated and sourced from OptoSigma. This lens is designed for use in spherical applications and features a base shape of a circle. The lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion.

The lens has a center thickness of 2.5 mm and an edge thickness of 1.7 mm, providing a robust structure suitable for various optical applications. The effective focal length (EFL) of this lens is 15.4 mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity.

The first radius of curvature (R1) is 15.57 mm, and the second radius of curvature (R2) is -15.57 mm, indicating the lens's double-convex shape. The back focal length (BFL) is 14.6 mm, which is the distance from the lens's rear surface to the focal point.

This lens is uncoated, meaning it does not have any additional layers to enhance light transmission or protect the lens surface. However, uncoated lenses can be more susceptible to environmental factors such as dust, dirt, and moisture.

The lens is designed for use at a wavelength of 546.1 nm. It's important to note that the performance of the lens can vary depending on the wavelength of light used.
