SLSQ-50-90N 50.0 mm Dia. x -90.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-50-90N is a Plano-Concave Lens with a diameter of 50.0 mm and a focal length of -90.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.
The lens geometry is characterized by its base shape, which is circular, and its spherical shape. The thickness at the edge of the lens is 11.4 mm, while the thickness at the center is 3 mm. The inner radius of the lens is 0 mm, and the outer radius is also 0 mm. The lens's effective focal length (EFL) is -90.0 mm, and the radius of curvature (R1) is -41.4 mm. The back focal length (BFL) is -92.1 mm.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it is still suitable for various applications where a Plano-Concave lens is required. The lens is in stock and can be purchased directly from the vendor's website, with the link provided in the item data.
