SLB-25.4-80PM 25.4 mm Dia. x 80.0 mm FL; Coated; Plano-Convex Lens 400-700nm

The SLB-25.4-80PM is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 80.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.

The lens geometry is characterized by its edge thickness of 1.9 mm and center thickness of 3.9 mm. The front and back surfaces of the lens are coated with opt m, a broadband anti-reflection coating that enhances transmission in the 400-700nm wavelength range. This coating reduces surface reflections, improving the overall efficiency and quality of the optical system.

The lens has a spherical shape with a radius of curvature of 41.52 mm on the convex side. The back surface of the lens is planar. The effective focal length (EFL) of the lens is 80 mm, and the back focal length (BFL) is 77.4 mm. The lens is designed to operate at a wavelength of 546.1 nm.
