SLSQ-40-250N 40.0 mm Dia. x -250.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-40-250N is a Plano-Concave Lens with a diameter of 40.0 mm and a focal length of -250.0 mm, making it a negatively powered lens. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is uncoated. The lens is made of fused silica, a material known for its excellent optical properties, durability, and resistance to thermal shock.
The lens's geometry includes a thickness edge of 3.8 mm and a thickness center of 2 mm, providing a sleek and compact design. 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 lens is defined by a radius of 115 mm on the curved surface.
The lens is designed to operate at a wavelength of 546.1 nm, which is within the visible light spectrum. It is important to note that the lens does not have any coating, which may affect its performance in certain applications. However, its uncoated nature can make it more cost-effective and suitable for applications where coating is not required or preferred.
