SLB-25-150N 25.0 mm Dia. x -150.0 mm FL; Plano-Concave Lens Uncoated

The SLB-25-150N is a Plano-Concave Lens with a 25.0 mm diameter and a focal length of -150.0 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 features a base shape of Circular and a Sub Type of Spherical Lens. The geometry of the lens includes a thickness edge of 3 mm and a thickness center of 2 mm. The lens's inner and outer radii are both 0, indicating a flat surface on one side and a concave surface on the other. The effective focal length (EFL) is -150.0 mm, and the radius of curvature (R1) is -77.85 mm. The back focal length (BFL) is -151.3 mm.

This lens is uncoated, meaning 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 have higher levels of surface reflection, which can impact the overall performance of the optical system.

The lens is designed to operate at a wavelength of 546.1 nm. It's suitable for use in a wide range of applications, including imaging systems, beam shaping, and laser applications.
