SLB-40-220PIR2 40.0 mm Dia. x 220.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-40-220PIR2 is a Plano-Convex Lens with a diameter of 40.0 mm and a focal length of 220.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality material known for its excellent optical properties.
The lens features a Plano-Convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The thickness at the edge of the lens is 2.0 mm, while the thickness at the center is 3.8 mm. The lens's effective focal length (EFL) is 220.0 mm, and the radius of curvature (R1) is 114.18 mm. The back focal length (BFL) is 217.5 mm, and the inner and outer radii are 0 mm.
The SLB-40-220PIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range. This coating ensures high transmission and low reflection, making the lens suitable for various applications in this spectral range.
