SLB-25.4-40PM 25.4 mm Dia. x 40.0 mm FL; Coated; Plano-Convex Lens 400-700nm
The SLB-25.4-40PM is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 40 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's geometry is characterized by a thickness of 1.9 mm at the edge and 6.2 mm at the center. The front and back surfaces of the lens are coated with an opt m coating, designed to enhance transmission in the 400-700nm wavelength range. This coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.
The lens's shape is spherical, with a radius of curvature of 20.76 mm on the curved (convex) surface. The back surface is flat (plano), making this lens suitable for a wide range of optical applications. The lens's effective focal length (EFL) is 40 mm, and the back focal length (BFL) is 36 mm.
