SLB-40B-90PIR2 40.0 mm Dia. x 91.1 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-40B-90PIR2 is a 40.0 mm diameter, double-convex lens with a focal length of 91.1 mm, specifically designed for use within the wavelength range of 750-1550nm. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical components.
The lens is made from n-bk7 schott, a popular material in the optical industry due to its excellent optical properties. The base shape of the lens is circular, and it features a spherical geometry with a center thickness of 6.3 mm and an edge thickness of 2 mm. The effective focal length (EFL) is 91.1 mm, while the back focal length (BFL) is 88.9 mm. The radii of curvature for the first and second surfaces are 93.42 mm and -93.42 mm, respectively.
The SLB-40B-90PIR2 is coated with Opt IR2 on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating helps to reduce reflection and increase transmission, making it ideal for use in various applications such as imaging, beam shaping, and laser systems.
