SLB-05B-20PM 5.0 mm Dia. x 20.2 mm FL; Coated; Double-Convex Lens 400-700nm
The SLB-05B-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 5.0 mm. The edge thickness measures 1.1 mm, while the center thickness is 1.4 mm, providing a robust structure for reliable performance. The effective focal length (EFL) of this lens is 20.2 mm, and the back focal length (BFL) is 19.8 mm, offering a long focal length for enhanced optical performance.
The lens is made from n-bk7 schott material, a popular choice in the optical industry due to its excellent optical properties. The lens's shape is spherical, with radii of curvature R1 and R2 being 20.76 mm and -20.76 mm, respectively. This shape ensures minimal spherical aberration and high-quality imaging.
The SLB-05B-20PM lens comes with a coating on both the front and back surfaces, specifically an opt m coating. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
