SLB-25-100N 25.0 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated

The SLB-25-100N is a Plano-Concave Lens, uncoated, with a 25.0 mm diameter and a focal length of -100.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion.

The lens's geometry is characterized by a thickness edge of 3.5 mm and a thickness center of 2 mm. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a flat surface on one side and a concave surface on the other. The lens's curvature is defined by a radius of curvature (R1) of -51.9 mm. The back focal length (BFL) is -101.3 mm, and the effective focal length (EFL) is -100.0 mm.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This may result in a lower transmission rate and a higher susceptibility to environmental factors compared to coated lenses. However, uncoated lenses are often chosen for their cost-effectiveness and simplicity.

The lens is designed to operate at a wavelength of 546.1 nm. It is spherical in shape, a common choice for its ease of manufacturing and versatility. The lens is available for purchase through the vendor's website, where it is currently listed as in stock.
