The SLB-25-80PIR2 is a Plano-Convex lens with a diameter of 25.0 mm and a focal length of 80.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a 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 curvature of the lens is defined by a radius of 41.52 mm on the curved side. The lens has an effective focal length (EFL) of 80 mm and a back focal length (BFL) of 77.4 mm. The thickness at the edge of the lens is 2 mm, while the thickness at the center is 3.9 mm.
The SLB-25-80PIR2 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.
