SLB-25.4-250P 25.4 mm Dia. x 250.0 mm FL; Plano-Convex Lens Uncoated

The SLB-25.4-250P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 250.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a high-quality glass known for its excellent optical properties.

The lens geometry is characterized by its diameter, thickness edge, and thickness center. The diameter is 25.4 mm, the thickness edge is 2 mm, and the thickness center is 2.6 mm. The effective focal length (EFL) is 250 mm, and the radius of curvature (R1) is 129.75 mm. The back focal length (BFL) is 248.3 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. 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 to work with a wavelength of 546.1 nm, making it suitable for a wide range of optical applications. Its spherical shape ensures excellent image quality and low distortion, making it a versatile choice for many optical systems.
