SLB-40-400PIR2 40.0 mm Dia. x 400.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-40-400PIR2 is a Plano-Convex lens, a type of spherical lens, with a diameter of 40.0 mm and a focal length of 400.0 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 optical glass, and features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex).
The lens has a thickness of 2.0 mm at the edge and 3.0 mm at the center. The effective focal length (EFL) is 400.0 mm, and the radius of curvature (R1) is 207.6 mm. The back focal length (BFL) is 398.0 mm, and both the inner and outer radii are 0.0 mm.
The SLB-40-400PIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the wavelength range of 750-1550nm. This coating ensures high transmission and low reflection, making it suitable for various applications in this spectral range.
