SLB-50-170N 50.0 mm Dia. x -170.0 mm FL; Plano-Concave Lens Uncoated

The SLB-50-170N is a Plano-Concave Lens, part of the Spherical Lens category, sourced from OptoSigma. This lens, with a diameter of 50.0 mm, is designed for use in systems where a negative focal length is required. The lens has a center thickness of 3.0 mm and an edge thickness of 6.6 mm, providing a robust structure suitable for various applications.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high chemical resistance. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be a good choice for applications where cost-effectiveness is a priority, or when specific coating requirements are not needed.

The effective focal length (EFL) of this lens is -170.0 mm, making it suitable for use in imaging systems where a reduced image size is desired. The lens's front and back radii are -88.23 mm and -172 mm, respectively, contributing to its concave shape. The lens does not have an inner or outer radius, indicating a uniform curvature throughout.

This lens is designed to work with a wavelength of 546.1 nm, a common choice for many optical systems due to its location in the visible spectrum. The lens's geometry and material make it suitable for use in a wide range of applications, including but not limited to, imaging, beam shaping, and laser applications.
