SLB-15B-100P 15.0 mm Dia. x 100.4 mm FL; Double-Convex Lens Uncoated

The SLB-15B-100P is a double-convex lens with a diameter of 15.0 mm and a focal length of 100.4 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 material known for its excellent optical properties.

The lens features a base shape of a circle, with a thickness of 2.0 mm at the edge and 2.5 mm at the center. The effective focal length (EFL) is 100.4 mm, while the back focal length (BFL) is 99.6 mm. The radii of curvature for the first and second surfaces are 103.8 mm and -103.8 mm, respectively.

This lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in certain applications where the natural properties of the glass are desired, or where cost considerations are a factor. However, it's important to note that uncoated lenses can suffer from increased reflection, which can reduce transmission and lead to unwanted ghosting or flaring effects.

The lens is designed to operate at a wavelength of 546.1 nm. It has a spherical geometry, which is a common shape for lenses due to its ease of manufacturing and good optical performance.
