SLB-40-350PIR2 40.0 mm Dia. x 350.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-40-350PIR2 is a Plano-Convex lens, a type of spherical lens, with a diameter of 40.0 mm and a focal length of 350.0 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, meaning one side is flat while the other is curved.
The lens has a thickness of 2.0 mm at the edge and 3.1 mm at the center. The inner radius is 0 mm, and the outer radius is also 0 mm. The back focal length (BFL) is 348 mm, and the effective focal length (EFL) is 350 mm. The radius of curvature (R1) is 181.65 mm.
The SLB-40-350PIR2 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 it suitable for various applications in this spectral range.
