SLB-25.4-150N 25.4 mm Dia. x -150.0 mm FL; Plano-Concave Lens Uncoated
The SLB-25.4-150N is a Plano-Concave Lens with a 25.4 mm diameter and a focal length of -150.0 mm, sourced from OptoSigma. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens is uncoated, offering a cost-effective solution for applications where coating is not a necessity.
The lens geometry includes a 3 mm thickness at the edge and a 2 mm thickness at the center, with an inner radius of 0 mm and an outer radius of 0 mm. The back focal length (BFL) is -151.3 mm, and the effective focal length (EFL) is -150 mm. The curvature radius (R1) is -77.85 mm.
This lens is ideal for applications that require a concave lens, such as beam expanding or collimating systems. It is also suitable for use in laser applications, interferometry, and imaging systems. The uncoated surface allows for easy cleaning and handling, making it a practical choice for various optical setups.
