SLB-07B-20PM 7.0 mm Dia. x 20.4 mm FL; Coated; Double-Convex Lens 400-700nm

The SLB-07B-20PM is a high-quality spherical lens, specifically a double-convex lens, sourced from 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 7.0 mm. The edge thickness measures 1.7 mm, while the center thickness is 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 optical glass due to its excellent optical properties and chemical durability. The lens is coated with Opt M on both the front and back surfaces, which enhances its performance in the specified wavelength range.

Please note that the inner and outer radii are both 0, indicating that this lens does not have any special shaping or beveling on its edges. This lens is a standard spherical lens, making it a versatile and reliable choice for many optical systems.
