SLB-25.4-50NM 25.4 mm Dia. x -50.0 mm FL; Coated; Plano-Concave Lens 400-700nm
This is a Plano-Concave Spherical Lens, sourced from OptoSigma, designed for use within the wavelength range of 400-700nm. The lens has a base shape of a circle, with a diameter of 25.4mm and a thickness at the edge of 5.3mm. The center thickness of the lens is 2mm, and it has an effective focal length (EFL) of -50mm. The lens's front radius of curvature (R1) is -25.95mm, and the back focal length (BFL) is -51.3mm.
The lens is made from n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The lens's coating is Opt M, applied to both the front and back surfaces to enhance its optical performance. This coating helps to reduce reflection and increase transmission, making the lens suitable for various applications.
