SLB-50B-150PIR2 50.0 mm Dia. x 151.2 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-50B-150PIR2 is a high-quality double-convex lens, designed and manufactured by OptoSigma. This lens, with a diameter of 50.0 mm and a focal length of 151.2 mm, is made from the renowned material n-BK7 Schott, ensuring excellent optical performance.
The lens features a double-convex geometry, with radii of curvature of 155.7 mm and -155.7 mm for the first and second surfaces, respectively. This geometry results in a back focal length of 148.8 mm and an effective focal length of 151.2 mm. The lens has a thickness of 3 mm at the edge and 7 mm at the center, providing robustness and durability.
The SLB-50B-150PIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance in the 750-1550nm wavelength range. This coating reduces reflection and increases transmission, making it ideal for applications such as IR imaging, spectroscopy, and beam shaping.
