SLB-25.4-80N 25.4 mm Dia. x -80.0 mm FL; Plano-Concave Lens Uncoated

The SLB-25.4-80N is a Plano-Concave Lens with a 25.4 mm diameter and a focal length of -80.0 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 4 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) of the lens is -80.0 mm, and the back focal length (BFL) is -81.3 mm.

The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may result in higher reflective losses and lower transmission compared to coated lenses. However, uncoated lenses are often more cost-effective and can be suitable for applications where such losses are acceptable or can be mitigated.

The lens is designed for use at a wavelength of 546.1 nm. It is in stock and ready for immediate shipping, as indicated by the "weblink status" field in the item data.
