The SLB-50-400PIR1 is a Plano-Convex lens, a type of spherical lens, with a diameter of 50.0 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 and the other side is curved.
The lens has a thickness of 3.0 mm at the edge and 4.5 mm at the center. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating a symmetrical curvature. The effective focal length (EFL) is 400 mm, and the back focal length (BFL) is 397 mm. The radius of curvature (R1) is 207.6 mm.
The SLB-50-400PIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the wavelength range of 633-1064 nm. This coating ensures high transmission and low reflection, making the lens suitable for various applications in this wavelength range.
