SLB-50-220N 50.0 mm Dia. x -220.0 mm FL; Plano-Concave Lens Uncoated

The SLB-50-220N is a Plano-Concave Lens, part of the Spherical Lens category, sourced from OptoSigma. This lens is characterized by its circular base shape and uncoated surface. The lens has a diameter of 50.0 mm and a center thickness of 3.0 mm, with an edge thickness of 5.8 mm. The effective focal length (EFL) of this lens is -220.0 mm, making it a negative or diverging lens.

The lens's concave surface has a radius of curvature (R1) of -114.18 mm, and the back focal length (BFL) is -222.0 mm. The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens is designed to operate at a wavelength of 546.1 nm.

The lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means the lens is more cost-effective and suitable for applications where such coatings are not necessary.
