SLB-25B-200PM 25.0 mm Dia. x 200.5 mm FL; Coated; Double-Convex Lens 400-700nm

The SLB-25B-200PM is a high-quality lens from OptoSigma, designed for use in the 400-700nm wavelength range. This lens is a spherical, biconvex design, featuring a diameter of 25.0 mm and a focal length of 200.5 mm. The lens is made from n-bk7 schott, a popular material for optical elements due to its excellent optical properties.

The lens has a center thickness of 2.8 mm and an edge thickness of 2 mm, providing a robust and durable design. The effective focal length (EFL) is 200.5 mm, and the back focal length (BFL) is 199.5 mm. The radii of curvature for the first and second surfaces are 207.6 mm and -207.6 mm, respectively. The lens does not have any inner or outer radius.

The SLB-25B-200PM is coated with an opt m coating on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission in the specified wavelength range. The lens is designed for use in a wide range of applications, including imaging, beam shaping, and laser systems.
