The SLB-80-500PIR1 is a Plano-Convex lens, sourced from OptoSigma, with a diameter of 80.0 mm and a focal length of 500.0 mm. This lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, making it suitable for a wide range of applications.
The lens features a coating of opt IR1 on both the front and back surfaces, enhancing its performance in the infrared spectrum, specifically between 633 and 1064 nm. This coating reduces surface reflections and increases transmission, making it ideal for use in IR imaging systems, spectroscopy, and other applications where high transmission and low reflection are required.
The geometry of the lens includes a thickness of 3.0 mm at the edge and 6.1 mm at the center, with an effective focal length (EFL) of 500.0 mm. The radius of curvature for the first surface (R1) is 259.5 mm, and the back focal length (BFL) is 496.0 mm. The lens has no inner or outer radius, indicating a uniform curvature.
