SLSQ-20-50N 20.0 mm Dia. x -50.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-20-50N is a Plano-Concave Lens with a diameter of 20.0 mm and a focal length of -50.0 mm, making it a negatively powered lens. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is made of fused silica, a material known for its excellent optical properties and durability.
The lens geometry includes a thickness edge of 4.3 mm and a thickness center of 2 mm, providing a robust structure. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a curved surface on the other. The curvature of the curved surface is represented by a radius of 23 mm.
The lens is designed to operate at a wavelength of 546.1 nm, which is within the visible light spectrum. It is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This lens is available for purchase and is currently in stock, according to the vendor's website.
