SLB-25.4-250PM 25.4 mm Dia. x 250.0 mm FL; Coated; Plano-Convex Lens 400-700nm
This is a Plano-Convex lens, type SLB-25.4-250PM, sourced from OptoSigma. The lens has a diameter of 25.4 mm and a focal length of 250 mm, making it suitable for a wide range of optical applications. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.
The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other side is curved (Convex). The radius of curvature for the curved side is 129.75 mm. The lens has an edge thickness of 2 mm and a center thickness of 2.6 mm. The back focal length is 248.3 mm, and the effective focal length is 250 mm.
The lens is coated with Opt M on both the front and back surfaces, enhancing its performance in the 400-700 nm wavelength range. This coating reduces reflection and increases transmission, making the lens ideal for use in laser applications and other settings where high transmission is required.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website or contact 3DOptix directly.
