The SLB-40-70PIR1 is a Plano-Convex lens, a type of spherical lens, with a diameter of 40.0 mm and a focal length of 70.0 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 8.0 mm at the center. The effective focal length (EFL) is 70.0 mm, and the radius of curvature (R1) is 36.33 mm. The back focal length (BFL) is 64.7 mm, and both the inner and outer radii are 0 mm.
The SLB-40-70PIR1 is coated with opt ir1 on both the front and back, providing enhanced performance in the wavelength range of 633-1064nm. This coating ensures optimal light transmission and reduces surface reflections, making it suitable for various applications.
