SLB-08B-20PM 8.0 mm Dia. x 20.4 mm FL; Coated; Double-Convex Lens 400-700nm

The SLB-08B-20PM is a high-quality double-convex lens, sourced from the reputable vendor OptoSigma. This lens is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.

The lens features a base shape of a circle, with a diameter of 8.0 mm. The edge thickness is 1.5 mm, while the center thickness measures 2.3 mm. The effective focal length (EFL) of this lens is 20.4 mm, and the back focal length (BFL) is 19.6 mm. The radii of curvature for the first and second surfaces are 20.76 mm and -20.76 mm, respectively.

The lens is made from n-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. The lens is coated with Opt M on both the front and back surfaces, enhancing its performance and durability.

This lens is a spherical lens, which is a type of lens where the two surfaces are parts of spheres. The curvature of the surfaces determines the focal length of the lens. In this case, the double-convex design of the lens (where both surfaces are convex) provides a positive focal length.

The item data also indicates that this lens is in stock and available for immediate purchase. For more detailed information, including pricing and availability, please refer to the vendor's website using the provided weblink.
